How to use Radio Group Widget

Content properties​

These properties are customizable options present in the property pane of the widget, allowing users to modify the widget according to their preferences.

Data​

Options array<object>​

This property allows you to set the labels and values for the items. You can add these labels and values directly from the user interface. Ensure that the values assigned to each option are unique. Additionally, you can turn on JS and provide options in JSON format, like:

Example:

[
  {
    "label": "Yes",
    "value": "yes"
  },
  {
    "label": "No",
    "value": "no"
  }
]

You can also dynamically display data by using JavaScript. For instance, you can use the .map() function to transform the data to the desired format, like:

Example:

{{getdata.data.map( p => ({label: p.country, value: p.country}))}}

Default selected value string​

This option allows you to set a default value in a widget, which is initially selected unless the user changes it.

Label​

Text string​

Sets the label on the widget.

Position string​

This property allows you to configure the label's placement.

Options:

  • Auto: Automatically positions the label based on the widget type and layout.
  • Left: Aligns the label to the left side of the widget.
  • Top: Positions the label above the widget.

Alignment string​

This property is only available when you select Left from the Position property. It allows you to align the text to the left boundary or adjust it closer to the widget using the Right alignment option.

Width number​

This property is only available when you select Left from the Position property. It allows you to control the proximity of the text to the widget, determining how close or far it can be positioned.

Validations​

Required boolean​

When enabled, this property makes the Radio Group a mandatory field. When the Radio Group is placed within a Form widget, enabling the Required property ensures that the Form's submit button remains disabled until the Radio Group has some value.

General​

Tooltip String​

This feature enables you to add hints or provide additional information to guide the user regarding the required input.

Visible Boolean​

This property controls the visibility of the widget. If you turn off this property, the widget would not be visible in view mode. Additionally, you can use JavaScript by clicking on JS next to the Visible property to conditionally control the widget's visibility.

Disabled Boolean​

This property prevents users from selecting the widget. Even though the widget remains visible, user input is not permitted. Additionally, you can use JavaScript by clicking on JS next to the Disabled property to control the widget's disable state conditionally.

Inline Boolean​

When this property is turned on, the radio items are displayed horizontally. However, when the property is turned off, the radio items are displayed in a vertical line.

Animate Loading Boolean​

This property controls whether the widget is displayed with a loading animation. When enabled, the widget shows a skeletal animation during the loading process. Additionally, you can control it through JavaScript by clicking on the JS next to the property.

Height String​

This property determines how the widget's height adjusts to changes in its content. There are three available options:
  • Fixed: The height of the widget remains as set using drag and resize.
  • Auto Height: The widget's height adjusts dynamically in response to changes in its content.
  • Auto Height with limits: Same as Auto height, with a configurable option to set the minimum and maximum number of rows the widget can occupy.

Events​

onSelectionChange​

This event defines the action that would be executed when the user selects or deselects item in the Radio Group. It allows you to specify a list of actions that can be triggered in response to the widget state change.

Style properties​

Style properties allow you to change the look and feel of the widget.

Font color String​

Represents the text color of the widget, specified as a CSS color value. It can also be manipulated programmatically using the JavaScript functions.

Font size String​

Determines the font size of the label. It accepts CSS font-size values and can also be programmatically modified using JavaScript functions.

Reference properties​

These properties are not available in the property pane, but can be accessed using the dot operator in other widgets or JavaScript functions. For instance, to get the visibility status, you can use RadioGroup1.isVisible.

Methods​

Widget property setters enable you to modify the values of widget properties at runtime, eliminating the need to manually update properties in the editor.

These methods are asynchronous and return a Promise. You can use the .then() block to ensure execution and sequencing of subsequent lines of code in Appsmith.

Sets the visibility of the widget.

RadioGroup1.setVisibility(true)

setDisabled (param: boolean): Promise​

Sets the disabled state of the widget.

Example:

RadioGroup1.setDisabled(false)

setData (param: array<object>): Promise​

Allows you to dynamically set the data of the widget.

Example:

RadioGroup1.setData([{ label: 'Option 1', value: 'option1' }, { label: 'Option 2', value: 'option2' }])
