Important Note!

Note that the option of creating new apps with the Ionic 4 framework was removed and we no longer support the projects that were created with it earlier.
Moreover, you are free to effortlessly migrate your Ionic 4 project(s) to their Ionic 5 version with keeping both apps active.
Please check this page to learn how to do it.

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:

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:

📘

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:

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:

📘

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:

🚧

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:

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:

📘

Please check these tutorials that explain how to use ngx-datatable in Ionic 4 apps:
https://docs.appery.io/docs/ionic-4-ngx-datatable-sample-tutorials.

DataTableCol

To add a DataTableCol, click the + button on the DataTable.
The DataTableCol component has the following properties:

Datetime

The Datetime component is used to present an interface that makes it easy for users to select dates and times.

Properties

The Datetime component has the following properties:

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

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:

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

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

2. 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:

1. 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.
2. 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.
3. 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.

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

🚧

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();

Properties

The Icon component has the following properties:

Visit the Ionic 4 documentation to learn more about Icons.

Image

Image is a tag that will lazily load an image whenever the tag is in the view port. This is extremely useful when generating a large list as images are only loaded when they're visible. The component uses Intersection Observer internally, which is supported in most modern browsers, but falls back to a set timeout when it is not supported.

Properties

The Image component has the following properties:

📘

Properties Responsive and Shape work only for default images but not for Ionic 4 images and wrapped images.

Visit the Ionic documentation to read more about Images.

Input

The Input component is a wrapper to the HTML input element with custom styling and additional functionality. It accepts most of the same properties as the HTML input does and works great on desktop devices and integrates with the mobile devices keyboards.

Using Input as a Form Control

📘

Use the following description only when the Form component has the disabled Native Validation property. With the Native Validation property enabled, the control can be used as a default HTML Form Control.

Input becomes a Form Control if it is included in a Form component and has the specified Name property. By default, the Name property is set as the Component name property but can be changed.

To set the control initial value, 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 null.

🚧

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

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:

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

📘

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

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.

🚧

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 Range component has the following properties:

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

Search

Searchbars represent text fields that can be used to search through a collection. They can be displayed inside of a toolbar or the main content.

Search should be used instead of an Input to search lists. A clear button is displayed upon entering input in the searchbar's text field. Clicking on the clear button will erase the text field and the input will remain focused. A cancel button can be enabled which will clear the input and lose the focus upon clicking.

Properties

The Search component has the following properties:

Visit the Ionic documentation to read more about Searchbar.

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.

Using Toggle 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

🚧

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 or null. If the property isn't specified the initial value will be 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.
