Introduction

When you build an app in Appery.io, you create pages (called Screens) that contain UI components such as buttons, inputs, checkboxes, lists, etc. All of the available UI components can be found on the PALETTE panel:

Each component, as well as the page itself, contains properties that can be changed:

1593 — Properties of the **Button** component

PROPERTIES Overview

Every component has a set of properties some of which are general, others are specific to particular components. All properties that are available for a particular component can be accessed from the PROPERTIES view on the right of the working area.
Here is the description of the properties that can be defined for most PALETTE components.
To check for the properties of a particular UI component, please see the documentation for the corresponding component; for example, the details of the Chart component can be found here.

📘
Most properties are provided with their corresponding ? tooltips: by hovering over them, you can get information on the property and how to use it.

General Components Properties

Every Appery.io UI component has its properties; some are general, others are specific to particular components. General properties belonging to most components available in the Visual App Builder include:

Property Name	Property Description
Class	List classes here.
Color	Color to use from your application's color palette. Value types: primary, secondary, tertiary, success, warning, danger, light, medium, dark).
Component Name	The mandatory property used for identifying the component. When you drag and drop the component from the components PALETTE the Appery.io Visual Builder gives it a standard name (e.g. GoogleMap1, Image1, etc.). It’s beneficial to rename the components so that you could easily identify them. This property exists inside the Visual Editor only and does not have any reflection in an application.
Disabled	Every component on the page is enabled by default. You may need to disable components. If set to true, the user cannot interact with the component.
Icon	Some components support icons. To choose the icon you need, expand Icon and click the No icon button for Style.
Attribute name	A new attribute value.
Mode	Determines which platform styles to use. Possible values are iOS or MD.
Slot	Position inside another component. It can be set to Fixed. Some components can have different settings: Start or End.

📘
You can select and manage components using Breadcrumbs or the OUTLINE view.

Button

Buttons provide clickable elements used in forms or anywhere where simple, standard button functionality is required.

Properties

Being the most popular component, the Button component can be used to navigate to a page or link, copy a property to a local storage variable or set the other component’s property, open and close popups, invoke a service, or run JavaScript. It may display text, icons, or both. Buttons can be styled with several attributes to look a specific way:

Property Name	Property Description
Back Button	Default Href* - the URL to navigate back to by default when there is no history. Icon- icon name to use for the back button; Click the Default icon*** button to select an icon, or leave it to default. Text* - text to display in the back button.
Button Type	Click to select between Button (default) or Bar Button.
Component	Use this property to change the button role for interaction with Menu (Ionic Menu Button) or Routing (Ionic Back Button): Ionic Button Ionic Menu Button Ionic Back Button. Navigation with Routing* has higher priority than Href.
Expand	Set to Block for a full-width button or to Full for a full-width button without left and right borders.
Fill	Set to Solid or select Clear for a transparent button, or Outline for a transparent button with a border.
Icon	Makes a button look like an icon. This property converts the button to an icon by changing its Style property and ignoring the Text property. Name* allows changing Ionic 4 icon style dynamically by property binding to [name]. Slot- position inside the button: Icon only,Start,End**. Style- click No icon** to change the icon style by selecting a needed icon. Mode- determines which platform styles to use. Possible values are iOSorMD***.
Link Features	Options for the component to be used as a link: Download* - instructs browsers to download a URL instead of navigating to it, so the user will be prompted to save it as a local file. If the attribute has a value, it is used as the pre-filled file name. Href* - contains a URL or a URL fragment that the hyperlink points to. If this property is set, an anchor tag will be rendered. Rel- specifies the relationship of the target object to the link object. Target- specifies where to display the linked URL. Only applies when anHrefis provided: Blank,Self,Parent, orTop*** Typeof the Button: Submit,Reset,Button***.
Menu Button	Auto Hide* - automatically hides the menu button when the corresponding menu is not active. Menu- an optional property that maps to a Menu's menuIdproperty. It can also bestartorend*** for the menu side. It is used to find the correct menu to toggle.
Routing	Route Name- defines the list of routes names from theRouting* panel. Route Params- the field used to add values forRoute Paramsdescribed in theRouting* panel. Router Direction- when using a router, it specifies the transition direction (back,forwardorroot) when navigating to another page usinghref*.
Shape	Setting to Round makes the button rounded.
Size	Select the preferred button size: Small, Defaultor Large.
Strong	If set to True, activates a button with a heavier font weight.
Text	Button text.
(click)	Action to be triggered when the button is clicked.

Common Chart Component Properties

The Chart component has the following properties that apply to all chart types:

Property Name	Property Description
Auto init Chart	If set to true, the Chart component is automatically initiated.
Class	Adds CSS classes for chart wrapper (class will not modify the chart canvas).
Labels	The array of labels to display. To specify it, switch to the CODE tab, add a variable, ex. label of Any type and provide the value(s) to be displayed in the chart: For example: `['Label 1', 'Label 2', 'Label 3', 'Label 4', 'Label 5']` (for simple labels) or `[ ['Label 1', 'value: 3'], 'Label 2', 'Label 3', 'Label 4', ['Label 5', 'Value: 5'] ]` (for multilabels). Now, the Labels property can be defined with the label value.
Type	Select the type of chart to be created: line* (default), bar, horizontal bar, radar, pie, doughnut, polarArea, bubble, scatter,mixed.
Show Advanced Properties	If set to true, the advanced chart properties can be accessed: All - all the advanced properties are available. Animation - animates charts out of the box. A number of options are provided to configure how the animation looks and how long it takes: duration* - the number of milliseconds the animation takes easing- the easing function to be used. Possible values are linear,easInQuad,easeOutQuad,easeInOutQuad,easeInCubic,easeInOutCubic,easeInQuart,easeOutQuart,easeInOutQuart,easeInQuint,easeOutQuint,easeInOutQuint,easeInSine,easeOutSine,easeInOutSine,easeInExpo,easeOutExpo,easeInOutExpo,easeInCirc,easeOutCirc,easeInOutCirc,easeInElastic,easeOutElastic,easeInOutElastic,easeInBack,easeOutBack,easeInOutBack,easeInBounce,easeOutBounce,easeInOutBounce*. Legend** - displays data about the datasets on the chart: Align- alignment of the legend (start,center(default for unrecognized values), orend**) Display- set to true** to display the legend Labels Box Width* - the width of the colored box Labels Font Color* - the text color Labels Font Size* - the text font size Labels Font Style* - the text font style Labels Use Point Style- the label style will match corresponding point style (size is based on the mimimum value betweenBox WidthandFont Size) Position- the legend position (top,left,bottom,right*) Reverse** - the legend will show datasets in reverse order Rtl- set to true* to render the legends from right to left. Title** - defines text to draw at the top of the chart: Display- set to true*** to display the title Font Color* - the font color Font Size* - the font size Font Style* - the font style Line Height* - the height of an individual line of text Padding* - the number of pixels to add above and below the title text Position- the title position (top,left,bottom,right**) Text - the title text to display. If specified as an array, text is rendered on multiple lines. Tooltips*: Background Color** - the tooltip background color Body Align- the horizontal alignment of the body text lines. ThetitleAlign,bodyAlignandfooterAlignoptions define the horizontal position of the text lines with respect to the tooltip box. The following values are supported: left(default),right,center. These options are only applied to text lines. Color boxes are always aligned to the left edge. Body Font Color* Body Font Size Body Font Style Body Spacing- the spacing to add to top and bottom of each tooltip item Border Color* Border Width* - the border size Caret Padding* - extra distance to move the end of the tooltip arrow away from the tooltip point Caret Size* - size, in `px`, of the tooltip arrow Corner Radius* - the radius of the tooltip corner curves Display- if set to true*** (default), the tooltips are enabled on canvas Display Colors- if set to true**, color boxes are shown in the tooltip Intersect- if set to true, the tooltip mode applies only when the mouse position intersects with an element. If set tofalse*, the mode will be applied at all times Mode** - sets which elements appear in the tooltip. When configuring interaction with the graph via hover or tooltips, a number of different modes are available. The modes and how they behave in conjunction with the intersect setting are detailed below: point* finds all of the items that intersect the point. nearest* gets the items that are at the nearest distance to the point. The nearest item is determined based on the distance to the center of the chart item (point, bar). You can use the axis setting to define which directions are used in distance calculation. If intersect is set to true, it is only triggered when the mouse position intersects an item in the graph. This is very useful for combo charts where points are hidden behind bars. index* finds item at the same index. If the intersect setting is true, the first intersecting item is used to determine the index in the data. If intersect is set to false the nearest item in the X direction is used to determine the index. To use index mode in a chart like the horizontal bar chart, where we search along the Y direction, you can use the axis setting introduced in `v2.7.0`. Setting this value to y on the Y direction is used. dataset* finds items in the same dataset. If the intersect setting is true, the first intersecting item is used to determine the index in the data. If intersect is set to false, the nearest item is used to determine the index. X* returns all items that would intersect based on the X coordinate of the position only. It would be useful for a vertical cursor implementation. Note that this only applies to cartesian charts. y* returns all items that would intersect based on the Y coordinate of the position. This would be useful for a horizontal cursor implementation. Note that this only applies to cartesian charts. MultiKey Background* - the color to draw behind the colored boxes when multiple items are in the tooltip Position* - the mode for positioning the tooltip. Possible modes are: average* will place the tooltip at the average position of the items displayed in the tooltip. nearest will place the tooltip at the position of the element closest to the event position. New modes can be defined by adding functions to the `Chart.Tooltip.positioners` map. Rtl- select true*** for rendering the legends from right to left Title Align- the horizontal alignment of the title text lines. ThetitleAlign,bodyAlignandfooterAlignoptions define the horizontal position of the text lines with respect to the tooltip box. The following values are supported: left(default),right,center. These options are only applied to text lines. Color boxes are always aligned to the left edge. Title Font Color* Title Font Size Title Font Style Title Margin Bottom* - the margin to add on the bottom of title section Title Spacing* - the spacing to add to top and bottom of each title line X Padding* - the padding to add on left and right of tooltip Y Padding* - the padding to add on top and bottom of the tooltip. Elements - while chart types provide settings to configure the styling of each dataset, you sometimes want to style all datasets the same way. A common example would be to stroke all of the bars in a bar chart with the same color but change the fill per dataset. Options can be configured for four different types of elements: line, arc, point, and rectangles. When set, these options apply to all objects of that type unless specifically overridden by the configuration attached to a dataset.

📘
The Radar and Polar Area charts also allow defining the following advanced properties:

Ticks

Grid Lines

Point Labels

Angle Lines

Please check our Chart component documentation to learn more.

🚧
All Elements properties are global properties for the selected Chart type.

The Chart component comes with a nested Chart Data component and the X/Y Axes Options components that can be added on clicking the corresponding gear icon within the selected chart.

Chart Data

The Chart Data component properties that are offered for setting heavily depend on what chart type is being defined.

There are also some Chart Data properties that apply to all chart types:

Property Name	Property Description
Data	The list of data value(s).
Legend Label	The label for the dataset which appears in the legend and tooltips. Not available for Polar Area, Pie and Doughnut chart types.
Order	The drawing order of dataset. Also affects order for stacking, tooltip, and legend. Not available forPolar Area, Pie and Doughnut chart types.
Axis ID	X Axis ID* - the ID of the X-axis to plot this dataset on. Y Axis ID- the ID of the Y-axis to plot this dataset on. Not available for Polar Area,Radar,Pie,Doughnut, andBubble* chart types.

📘
You can check our Chart component documentation page to learn about the properties specific to different chart types.

Chart Axes Options

Axes are an integral part of a chart. They are used to determine how data maps to a pixel value on the chart. In a cartesian chart, there is one or more X-axis and one or more Y-axis to map points onto the 2-dimensional canvas. These axes are know ascartesian axes.
In a radial chart, such as a radar chart or a polar area chart, there is a single axis that maps points in the angular and radial directions. These are known radial axes. You can learn more about radial charts Axes Options here.

🚧
The scales in Chart.js > v2.0 are significantly more powerful, but also different than those of v1.0.
Multiple X- & Y-axes are supported. A built-in label auto-skip feature detects would be overlapping ticks and labels and removes every nth label to keep things displaying normally.
Scale titles are supported. New scale types can be extended without writing an entirely new chart type.

Click the corresponding gear icon (X or Y) within the selected chart to add a new Axes Options element. Then, select it to get access to its properties.
X/Y Axes Options have the following properties:

Property Name	Property Description
Scales	Display- controls the axis global visibility if set to true**. Id- is used to link datasets and scale axes together. The propertiesdataset.xAxisIDordataset.yAxisIDhave to match the scale propertiesscales.xAxes.id** or scales.yAxes.id. This is especially needed if multi-axes charts are used. Labels** - the labels list: `['Label 1','Label 2','Label 3','Label 4','Label 5']`or `['Label 5','Label 1','Label 2','Label 3','Label 1']`. Position- the position of the axis in the chart. The possible values are: X Axes: top,bottom*** Y Axes: left,right**. Stacked- if set to true, data is stacked. Stacked area charts can be used to show how one data trend is made up of a number of smaller pieces. Bar charts can be configured into stacked bar charts by changing the settings on the X- and Y-axes to enable stacking. Type - the type of the scale to be used: linear, logarithmic, or category*: Linear** scale is used to chart numerical data. It can be placed on either the X- or Y-axis. The scatter chart type automatically configures a line chart to use one of these scales for the X-axis. As the name suggests, linear interpolation is used to determine where a value lies on the axis Logarithmic * scale is used to chart numerical data. It can be placed on either the X- or Y-axis. As the name suggests, logarithmic interpolation is used to determine where a value lies on the axis Category- if global configuration is used, labels are drawn from one of the label arrays included in the chart data. If only data.labels is defined, this will be used. Ifdata.xLabelsis defined and the axis is horizontal, this will be used. Similarly, ifdata.yLabelsis defined and the axis is vertical, this property will be used. Using bothxLabelsandyLabelstogether can create a chart that uses strings for both the X- and Y-axes. Specifying any of the settings above defines the X-axis as the category*** type if not defined otherwise. For more fine-grained control of category labels it is also possible to add labels as part of the category axis definition. Doing so does not apply the global defaults.
Grid Lines	The grid line configuration is nested under the scale configuration in the gridLines key. It defines options for the grid lines that run perpendicular to the axis. https://www.chartjs.org/docs/latest/axes/styling.html Border Dash* - the length and spacing of dashes on grid lines. Color* - the grid lines color. If specified as an array, the first color applies to the first grid line, the second to the second grid line and so on. Display- if set to false**, the grid lines for this axis will not be displayed. Draw Border- if set to true*, the border at the edge between the axis and the chart area is drawn. Draw On Chart Area- if set to true*, the lines on the chart area inside the axis lines are drawn. This is useful when there are multiple axes and you need to control which grid lines are drawn. Draw Ticks- if set to true*, the lines beside the ticks in the axis area beside the chart are drawn. Line Width** - the stroke width of grid lines. Offset Grid Lines- if set to true, the grid lines will be shifted to locate between the labels. This is set totrue* for thebar** chart by default. Tick Mark Length* - the length in `px` that the grid lines will draw into the axis area. Z-Index* - z-index of the grid line layer. The values `<= 0` are drawn under datasets, those that are ``> 0` on top. Zero Line Border Dash* - the length and spacing of dashes of the grid line for the first index (`index 0`). Zero Line Color* - the stroke color of the grid line for the first index (`index 0`). Zero Line Width* - the grid line stroke width for the first index (`index 0`).
Label	Display- if set to true**, displays the axis title. Font Color** - the font color for scale title. Font Size* - the font size for scale title. Font Style- the font style for the scale title, follows the CSS font-style options (i.e. normal,italic,oblique,initial,inherit**). Label String** - the text for the title. Line Height* - the height of an individual line of text. Padding* - the padding to apply around scale labels. Only top and bottom are implemented.
Ticks	Auto Skip- if set to true, automatically calculates how many labels can be shown and hides labels accordingly. Labels will be rotated up tomaxRotationbefore skipping any. TurnAuto Skip* off to show all labels available. Auto Skip Padding- the padding between the ticks on the horizontal axis withAuto Skip* enabled. Begin At Zero- if set to true**, the scale will include 0 if it is not already included. Display- controls the axis global visibility (visible when true, hidden whenfalse*). Font Color** - the font color for tick labels. Font Size* - the font size for the tick labels. Font Style* - the font style for the tick labels, follows the CSS font-style options. Label Offset* - the distance in `px` to offset the label from the center point of the tick (in the Xdirection for the X-axis, and theY* direction for the Y-axis). Note that this can cause labels at the edges to be cropped by the edge of the canvas. Line Height* - the height of an individual line of text. Max* - the user defined maximum number for the scale, overrides maximum value from data. Max Rotation* - the maximum rotation for tick labels when rotating to condense labels. Rotation doesn't occur until necessary. Only applicable to horizontal scales. Min* - the user defined minimum number for the scale, overrides minimum value from data. Min Rotation* - the minimum rotation for tick labels. Only applicable to horizontal scales. Mirror- flips tick labels around axis, displaying the labels inside the chart instead of outside. Only applicable to vertical scales. Padding- the padding between the tick label and the axis. When set on a vertical axis, this applies in the horizontal (X) direction. When set on a horizontal axis, this applies in the vertical (Y*) direction. Precision- if defined with theStep Size** property unspecified, the step size will be rounded to this many decimal places. Reverse- reverses the order of tick labels if set to True**. Sample Size** - the number of ticks to examine when deciding how many labels will fit. Setting a smaller value will be faster, but may be less accurate when there is large variability in label length. Step Size* - the user defined fixed step size for the scale. Ticks Max Ticks Limit* - the maximum number of ticks and gridlines to show. Z-index* - z-index of the tick layer. It is used when ticks are drawn on chart area. The values `<= 0` are drawn under datasets, those `> 0` on top.

🚧
For the linear Axes type Zero Line is 0!

Checkbox

Checkboxes allow the selection of multiple options from a set of options. They appear as checked (ticked) when activated. Clicking on a checkbox will toggle the checked property. They can also be checked programmatically by setting the checked property.

Using Checkbox as a Form Control

🚧
Use the following description only when the Form component has the disabled Native validation property. If the Native validation property is enabled the control can be used as a default HTML Form Control.

To set the initial value of the control, use the Initial Value property of the Form Control properties section. The component can have only boolean (true or false) values. If the property is not specified, the initial value will be set to null.

📘
If included in a Form component, Checkbox becomes a Form Control; the Name property should be specified (by default, the Name property is defined as the Component name property, so change it if necessary).

To use variables as the control's data, the advanced property [(ngModel)] should be specified - the variable name should be entered as the property value. It replaces the value that is set by the Initial Value property.

The component can get additional properties (Control ID and Control options) that allow checking the validity, changing updating strategy, etc. These properties can be used if the Native Validation property is disabled for the Form component.
Read more about validation in the Form section.

🚧
Note!
The component can't be used with array iteration data for creating a dynamic form structure. If you need to create such kind of structure, follow these recommendations

Properties

The Checkbox component has the following properties:

Property Name	Property Description
Indeterminate	If set to True, the checkbox will visually appear as indeterminate. The default is set to false.
Checked	If set to true, the checkbox is selected. The default is set to false.
Name	The name of the control, which is submitted with the form data.
Value	Used as data for forms and groups. The value of the checkbox does not mean if it is checked or not, use the checked property for that.
[(ngModel)]	Angular directive for data binding.
(ionBlur)	The event emitted when the toggle loses focus.
(ionChange)	The event emitted when the checked property has changed.
(ionFocus)	The event emitted when the toggle has focus.

DataTable

The DataTable component consists of DataTableCols the number of which can be changed by adding or cloning.

Properties

The DataTable component has the following properties:

Property Name	Property Description
Column Mode	Column modes allow having a variety of different ways to apply column width distribution to the columns using: Standard* - columns are distributed given the width is defined in the column options; Flex* - distributes the width's grow factor relative to other columns. It works the same as the flex-grow API in CSS. Basically, it takes any available extra width and distributes it proportionally according to each column's Flex Grow value. Flex is not suggested when the ScrollbarH property is set to True; Force* forces the widths of the columns to distribute equally but overflows when the min-width of each column is reached. Force is usually the ideal column distribution method when columns do not need to be fixed-sized.
Count	Enter the number to set the total count of all rows. The default is set to 0. The property is necessary for correct rows displaying in infinite scroll modes and for calculations for page navigation. Required if the Data Mode property is set to Server Pages or Server Infinite. If the Data Mode property is set to Client Pagesor Client Infinite, Count will be automaticallycalculated as the length of `Rows data.
Css Classes	Custom CSS classes that can be defined to override the icons classes for up/down in sorts and previous/next in the pager. If entered, custom classes for icons will replace existing classes. Value types: Pager Left Arrow- the default value is set to datatable-icon-left**; Pager Next- the default value is set to datatable-icon-skip*; Pager Previous- the default value is set to datatable-icon-prev*; Pager Right Arrow- the default value is set to datatable-icon-right*; Sort Ascending- the default value is set to datatable-icon-down*; Sort Descending- the default value is set to datatable-icon-up**.
Data Mode	Data source. Mode: Client Pages,Client Infinite,Server Pages, orServer Infinite**. Service Name- the service to be linked with the datatable to return data. It is created after a datasource is added under theDATA** tab.
Display Check	Can be used to check whether you want to show the checkbox for a particular row based on some criteria. Create a new function under the DATA tab of the Visual Editor and choose the created function for the property. `(row, column, value) => { return row.name !== 'Ethel Price'; }`
External Sorting	To be used instead of client-side sorting. The default is set to False.
Footer Height	The minimum footer height in pixels. This property is used for calculating the dimensions of the table size. Pass false value for no footer.
Header Hight	Minimum header height in pixels. Header Heightcan`t be auto* whenScrollbarVis Trueor Data Mode isClient InfiniteorServer Infinite or theScrollbarVproperty is set to True. It is automatically changed toundefinedfromauto** if the properties above are set.
Limit	Is necessary for calculating sizes (rows count) of the page and for pagination. If not defined, Limit will be calculated as the length of Rows data (one page with all rows data).
Messages	Static messages in the table that can be overridden for localization. Value types: Empty Message* - a message to show when an array with no values is presented; Selected Message* - footer selected message; Total Message* - footer whole message.
Offset	The current offset ( page - 1 ) is shown. The property is necessary for calculating the number of the current page. In this case, it will be the Offset property increased by 1. Should be set if the number of the first page differs from the default,
Reorderable	Enables/disables the ability to re-order columns by dragging them. Value type: boolean. The default value is set to True.
Row Class	The function used to populate a row's CSS class. The function will take a row and return a string or object. The value type is Function. It makes adding custom classes depending on specific conditions possible. Create a new function under the CODE tab of the Visual Editor and choose the created function for the property. `(row) => { return { 'old': row.age > 50, 'young': row.age <= 50, 'woman': row.gender === 'female', 'man': row.gender === 'male' } }`
Row Height	Is necessary for calculating the sizes of the page when infinite scrolling is used and it is optional for pagination mode. The default value is auto for Client Pages / Server Pages and 50 for Client Infinite / Server Infinite. When infinite scrolling is not used, pass undefined for fluid heights. If infinite scrolling is used, pass a number to calculate the heights. Row Heightcan`t be auto* when theData Modeproperty is set to Client InfiniteorServer Infinite or theScrollbarVproperty is set to True. It is automatically changed toundefinedfromauto** if the properties above are set.
Rows	An array of rows to display (variable or mapping). Value type: Array. The default value is set to []. There are two ways to set the data source for Rows: Define a variable under the CODE tab with data. Then choose the variable as the value for the property Rows; Use the DATA tab to map service data to the Rows property.
ScrollbarH	Enables / disables horizontal scrollbars. The default value is set to False.
ScrollbarV	Is necessary for infinite scrolling. Setting the property to True resets the Row Height and Header Height properties from auto to undefined because there are required defined heights values for correct table calculations. The default value is set to False.
Selection Type	The type of row selection. The value types are Single* - one row can be selected at a time; Cell* - one cell can be selected at a time; Multi - multiple rows can be selected using Ctrl or Shift keys; MultiClick* - multiple rows can be selected by clicking; Checkbox* - multiple rows can be selected using checkboxes.
Sorts	Is used to determine the default column for sorting. The default is set to empty (unsorted). Column Name* - enter text to name a column. Direction- set the sorting direction: asc(ascending) ordesc*** (descending).

Every new Datetime component is created with a default label and the current time value.

Using Datetime as a Form Control

📘
Datetime becomes a Form Control if included in a Form component and if it has the property Name specified. By default, the Name property is set as the Component name property. Change it to your name if it is necessary.

To use variables as the control's data, the advanced property [(ngModel)] should be specified - the variable name should be entered as the property value. It replaces the value that is set by the Initial Value property.

The component can get additional properties (Control ID and Control options) that allow checking the validity, changing updating strategy, etc. These properties can be used if the Native Validation property is disabled for the Form component.
Read more about validation in the Form section.

🚧
Note!
The component can't be used with array iteration data for creating a dynamic form structure. If you need to create such kind of structure, follow these recommendations

Visit the Ionic documentation to read more about Datetime.

Form

Handling user input with forms is the cornerstone of many common applications. Applications use forms to enable users to log in, update a profile, enter sensitive information, or to perform many other data-entry tasks.

The Form component is based on Angular template-driven forms.

Composition

The Form is a container including Form Control like Input, Radiobutton, Checkbox, Select etc.).
To create a Form Control, drag & drop a needed component from the components PALETTE of the Visual Editor.

🚧
The added component will become a Form Control only when the property Name is specified which defines control data key.
For example, we have an Input with defined Name = userName and value = Peter. In this case, the control data will be available as the property of the form data object: {userName: 'Peter'}.

Sending data

There are two ways to send form data:

Including the special Submit control. The control has to be placed inside the form:

<form>
    <ion-button type="submit">Submit</ion-button>
</form>

Using the Form submit action on the EVENTS panel. The control can be placed everywhere on the page.

Actions at the form submitting can be specified in three ways:

Using the Form submit event of the form component on the EVENTS panel (for beginners). In this case, a user can choose an action to be executed at the form submitting. For example, such action can be Invoke service (e.g. Login service) with specified mapping on the DATA tab.
Using the (ngSubmit) event of the component (for advanced users). In this case, a user has to define a function - handler which will execute submitting from custom code.
Using the Action property of the component (for advanced users). In this case, a user has to define the URL where form data will be sent.

Validation

By default, Ionic has own validation rules for controls included in the form. If you want to use the validity of the form in general, specify the property Form ID.
The word passed as the value of the property can be used as a variable containing information about the form. Such usage is described in the PROPERTIES section:
The Form ID property can be used as the variable containing the Form state (e.g. formID.valid and formID.value). To use it in custom code, add 'this.' prefix.

Form and Controls have different states when Ionic validation is used.

State	Description
valid	A control is considered valid if no validation errors exist with the current value. If the control is not present, null is returned.
invalid	An error exists in the input value. If the control is not present, null is returned.
pending	Async validation is occurring and errors are not yet available for the input value. If the control is not present, null is returned.
disabled	The control is disabled in the UI and is exempt from validation checks and excluded from aggregate values of ancestor controls. If the control is not present, null is returned.
enabled	The control is included in ancestor calculations of validity or value. If the control is not present, null is returned.
pristine	The user has not yet changed the value in the UI. If the control is not present, null is returned.
dirty	The user has changed the value in the UI. If the control is not present, null is returned.
touched	The user has triggered a blur event on it. If the control is not present, null is returned.
untouched	The user has not yet triggered a blur event on it. If the control is not present, null is returned.
errors	Reports the control's validation errors.

For example, check using the invalid input state to show an error message: <ion-text *ngIf="user.invalid" color="danger">Incorrect user name</ion-text>. In this case, user is a Control ID defined for the Input component.
If you need to use validation to specific errors, use the errors state with specifying the type of a validation error.

Let's see how different error messages at the Input component validation are displayed.
Define the Control ID property of the Input with the passControl value and set its validation (to required and pattern="[0-9]*", for example).
Add two components containing error messages and add the *ngIf directive as an advanced property with the value that is a condition for displaying the error component. The directive is used to show/hide components depending on a directive boolean value.

If the component is valid, the expression passControl.errors will return null (equal to false).
If the component is invalid, the expression passControl.errors will return the object containing all validation errors available by their names. The existence of a necessary error name in the returned errors object is used for the condition of displaying the error message.

<form #myForm="ngForm">
    <ion-input required pattern="[0-9]*" #passControl="ngModel" [ngModel] name="pass"></ion-input>
    <ion-text *ngIf="passControl.errors && passControl.errors.required" color="danger">Value has to be entered</ion-text>
    <ion-text *ngIf="passControl.errors && passControl.errors.pattern" color="danger">Value should contain only numbers</ion-text>
</form>

Properties


Novalidate	This boolean attribute indicates that the form shouldn't be validated when submitted.
Native validation	If set to True, native HTML5 validation is used instead of Angular validation. The form will work as the default HTML `<form>`.
Form ID	A unique word identifying the component (Template reference variable) that contains current form information. Used in component's properties as a variable containing the form state.
Update On	Controls when the value or the validity is updated: Change, Blur, Submit
Features	Advanced options containing default HTML form attributes. Action - the URL that processes the form submission. Specifies where to send the form-data when a form is submitted. Disabled if Form submit or (ngSubmit) is used. Enctype - specifies how the form-data should be encoded when submitting it to the server (only if Method is set to post). The Enctype property has the following options: application/x-www-form-urlencoded* - default. All characters are encoded before sent (spaces are converted to "+" symbols, and special characters are converted to ASCII HEX values); multipart/form-data* - no characters are encoded. This value is required when you are using forms that have a file upload control; text/plain* - spaces are converted to + symbols, but no special characters are encoded. Method specifies the HTTP method (get or post) to use when sending form-data: get* appends form-data into the URL in name/value pairs. The length of a URL is limited (about 3000 characters). Never use GET to send sensitive data! (will be visible in the URL), it is better used for non-secure data, like query strings in Google. Useful for form submissions where a user wants to bookmark the result. post* appends form-data inside the body of the HTTP request (data is not shown in URL). It has no size limitations. Form submissions with POST cannot be bookmarked. Target specifies where to display the response that is received after submitting the form: Blank* - the response is displayed in a new window or tab. Self* - the response is displayed in the same frame (default); Parent* - the response is displayed in the parent frame. Top* - the response is displayed in the full body of the window.
(ngSubmit)	The event emitted when the form is submitted. The event Form submit takes precedence over the Action property.

🚧
In the initial state of the component, the default HTML <form> features (Action, Target, etc.) are not supported because they are replaced with Angular functionality. To disable Angular functionality and enable default HTML behavior of the component, enable the Native validation property.

The Form ID property can be used in template or code as a variable containing information about the form:

formID = {
    value: boolean,   // Reports the value of the form
    valid: boolean,   // Reports whether the form is valid. A form is considered valid if no validation errors exist with the current value
    invalid: boolean, // Reports whether the form is invalid, meaning that an error exists in the value
    dirty: boolean    // Reports whether the form is dirty, meaning that the user has changed the value in the UI
  }

In templates, the Form ID property is used as a variable. It can be also passed as a function argument:

<ion-button disabled={{formID.invalid}} type="submit">Submit</ion-button>
  <ion-button (click)="send(formID)">Send</ion-button>

To be used in custom code, the variable is available as this.<Form ID>:

if (this.formID.valid) this.submit();

Radiobutton

Radiobuttons are generally used as a set of related options inside of a group, but they can also be used alone. Pressing on a radiobutton will check it. They can also be checked programmatically by setting the Checked property.
An ion-radio-group can be used to group a set of radiobuttons (or radios). When radios are inside of a radio group, only one radiobutton in the group will be checked at any time. Pressing a radiobutton will check it and uncheck the previously selected radiobutton, if there is one. If a radiobutton is not in a group with another radiobutton, then both radiobuttonss will have the ability to be checked at the same time.

Mapping

There is a possibility to use mapping to the Checked property of the component.
Such binding is used only for initializing the component when created dynamically.
If it is necessary to use dynamic changing of the checked state, the value of the checked button should be bound to the Value property of the Radio Group component in the mapping.

<ion-radio-group value="value2">
  <ion-radio value="value1"></ion-radio>
  <ion-radio value="value2"></ion-radio>
  <ion-radio value="value3"></ion-radio>
</ion-radio-group>

In this case, to check the value2 button by mapping, the binding to the Value property of the Radio Group component should return a string value2 which is equal to the Value property of the button.

Properties

The Radiobutton component has the following properties:

Property Name	Property Description
Value	The value of the input.
Checked	If set to true, the element is selected.
Name	The name of the control, which is submitted with the form data.
Slot	Radiobutton position in the `<ion-item>` tag (Start or End).
[(ngModel)]	Angular directive for data binding.
(ionSelect)	The event emitted when the radiobutton is selected.

When the Item Wrapped property is set to True, the component will be included in the Item with additional properties:

Property Name

Property Description

Item Wrapper

If the item wrapper features are used, the input will be wrapped in the <ion-item> tag.

*Lines- define how the bottom border should be displayed on the item. The available options are *Full,InsetorNone***.
*Mode** - label mode.
*Slot** - position inside another component.

Label

If the label is used, the input will be wrapped in the <ion-item> tag.

*Text ** - label text.
*Position- determines where and how the label behaves inside an item. The possible values are *Inline,Fixed,StackedorFloating***.
*Color** - label Ionic 4 color.

Reorder

Reorder properties:

*Type- *ContentorWrapper. IfWrapper*** is used, the item will be wrapped into the reorder tag.
*Icon- custom icon for reorder with type *Content***.
*Slot** - position inside the item.
*Custom SVG Icon** - an svg file can be selected. This path will be added as the src attribute.

📘
Using the following properties makes Radiobutton to a List Item:

Label Text is not empty;

Item Wrapper Color or Lines are set;

Reorder Type is Content or Wrapper.

Visit the Ionic 4 documentation to read more about Radiobuttons.

RadioGroup

The RadioGroup is a group of radiobuttons. It allows a user to select at most one radiobutton from a set. Checking one Radiobutton that belongs to a radio group unchecks any previously checked radiobutton within the same group.

The RadioGroup component is based on Ionic 4 ion-radio-group.

The RadioGroup is a container including a Radio Group Header and Radiobuttons. By default, the RadioGroup has 3 Radiobuttons. To insert more buttons, use the + button on the Radio group components or drag & drop a Radiobutton from the PALETTE to the Visual Editor canvas. Note that all Radiobuttons should have different value properties for correct work inside a RadioGroup.

You can add a header to your Radiogroup by setting the property Group Header to True.
To change the direction of radiobuttons, use the the Buttons direction property. The Horizontal direction is set by adding a CSS class of the flexbox styles.

🚧
A header can not be added when the Horizontal direction is used.

If you use the RadioGroup as a Form Control, the properties Name and [(ngModel)] should be defined. In this case, the Name property defines a key name of form data, and the [(ngModel)] property defines the name of the variable containing sent data.

For dynamic value changing, use [(ngModel)] instead of the Value property. In this case, a variable name containing changing value data as the value of the [(ngModel)] property should be passed.

Using RadioGroup as a Form Control

RadioGroup becomes the Form Control if it is included in a Form component and has the Name property specified. In this mode, the component has additional properties (Control ID and Control options that allow checking the validity, changing updating strategy, etc. These properties can be used only in the Form component doesn't have the Native validation property enabled.

To use variables as the control's data, the advanced property [(ngModel)] should be specified - the variable name should be entered as the property value. It replaces the value that is set by the Initial Value property.

The component can get additional properties (Control ID and Control options) that allow checking the validity, changing updating strategy, etc. These properties can be used if the Native Validation property is disabled for the Form component.
Read more about validation in the Form section.

🚧
Note!
The component can't be used with array iteration data for creating a dynamic form structure. If you need to create such kind of structure, follow these recommendations

Properties

The RadioGroup component has the following properties:

Property Name	Property Description
Value	The components's value.
Name	The name of the control, which is submitted with the form data.
Empty Selection	If set to True, radios can be deselected.

Group Header	If set to True, adds a header of the radio group. Hidden if the Horizontal direction is chosen.
Control ID	Name of the control. Used in components properties as the variable containing the control state.
Control Options	Advanced Form Control options. Update On* - controls when the value or the validity is updated. Standalone- when set to true***, the component will not register itself with its parent form but act as if it's not in the form.
[(ngModel)]	Angular directive for data binding.
(ionChange)	The event emitted when the value has changed.

For dynamic changing value use [(ngModel)] instead of the Value property.

The Radio Group Header has the following property:

Property Name	Property Description
Header text	The header text shown.

Range

The Range slider lets users select from a range of values by moving the slider knob. It can accept dual knobs, but by default one knob controls the value of the range

The component is based on Ionic 4 ion-range.

Using Range as a Form Control

🚧
Use the following description only when the Form component has the disabled Native validation property. If the Native validation property is enabled the control can be used as a default HTML Form Control.

To set the initial value of the control, use the Initial Value property of the Form Control properties section.

📘
If included in a Form component, Range becomes a Form Control; the Name property should be specified (by default, the Name property is defined as the Component name property, so change it if necessary).

The component can have a number value (e.g. 20) or an object value if the Dual Knobs property is True (e.g. { lower: 20, upper: 80 }). If the property isn't specified the initial value will be set to null.

To use variables as the control's data, the advanced property [(ngModel)] should be specified - the variable name should be entered as the property value. It replaces the value that is set by the Initial Value property.

The component can get additional properties (Control ID and Control options) that allow checking the validity, changing updating strategy, etc. These properties can be used if the Native Validation property is disabled for the Form component.

Select

Selects are (Form Controls) used to select an option or options from a set of options, similar to a native ion-select element. When the select is tapped, a dialog appears with all of the options in a large, easy to select list.
A select should be used with child ion-select-option elements. If the child option is not given a value attribute, then its text will be used as the value.
If the value is set on the ion-select, the selected option will be chosen based on that value. Otherwise, the selected attribute can be used on the ion-select-option.

📘
Basics about working with the Select component
You can find more information on how to work with Select here.

Mapping

There is a possibility to use mapping to the Selected property of its options.
Such binding is used only for initializing selected options when they are created dynamically.
If it is necessary to use dynamic selection for options, the value of the selected option should be bound to the Value property of the Select component in the mapping.

<ion-select value="value2">
  <ion-select-option value="value1">value1</ion-select-option>
  <ion-select-option value="value2">value2</ion-select-option>
  <ion-select-option value="value3">value3</ion-select-option>
</ion-select>

In this case, to select the value2 option by mapping, the binding to the Value property of the Select component should return a string value2 which is equal to the Value property of the option.

If the Multiple property is enabled, the mapping should return an array of values of options that should be selected (['value2', 'value3'])

Using Select as a Form Control

The component is the Form Control of Angular form when:

it is included into the Form component
the Form has the Native validation property disabled (is set to False)
it doesn't have the Standalone option under Control Options enabled
the component has the property Name specified

If the Native validation property is enabled, the control can be used as a default HTML Form Control.
By default, the Name property is set as the Component name property and can be customized.
To set the initial value of the control, use the Initial Value property of the Form Control properties section.
The component can have only string values or null. If the property isn't specified, the initial value will be set to null.

To use variables as the control's data, the advanced property [(ngModel)] should be specified - the variable name should be entered as the property value. It replaces the value that is set by the Initial Value property.

The component can get additional properties (Control ID and Control options) that allow checking the validity, changing updating strategy, etc. These properties can be used if the Native Validation property is disabled for the Form component.
Read more about validation in the Form section.

🚧
Note!
The component can't be used with array iteration data for creating a dynamic form structure. If you need to create such kind of structure, follow these recommendations.
