One or more variables that are updated with the choice index when the user changes the selection. Use a!save() to save a modified or alternative value to a variable.

Validation Group

validationGroup

Text

When present, the requiredness of the field is only evaluated when a button in the same validation group is pressed. The value for this parameter cannot contain spaces. For example, “validation group” is not a valid value. You need to add an underscore between words: “validation_group”. See the following recipes for more information:

Required Message

requiredMessage

Text

Custom message to display when the field's value is required and not provided.

Label Position

labelPosition

Text

Determines where the label appears. Valid values:

  • "ABOVE" (default) Displays the label above the component.
  • "ADJACENT" Displays the label to the left of the component.
  • "COLLAPSED" Hides the label. The label will still be read by screen readers; see accessibility considerations for more information.
  • "JUSTIFIED" Aligns the label alongside the component starting at the edge of the page.

Choice Layout

choiceLayout

Text

Determines the layout. Valid values: "STACKED" (default), "COMPACT".

Help Tooltip

Text

Displays a help icon with the specified text as a tooltip. The tooltip displays a maximum of 500 characters. The help icon does not show when the label position is "COLLAPSED".

Accessibility Text

accessibilityText

Text

Additional text to be announced by screen readers. Used only for accessibility; produces no visible change.

Visibility

showWhen

Boolean

Determines whether the component is displayed on the interface. When set to false, the component is hidden and is not evaluated. Default: true.

Choice Style

choiceStyle

Text

Determines how the choices should be displayed on the interface. Valid values: "STANDARD" (default), "CARDS".

Usage considerations

Using the choiceLabels parameter

  • Choices display in the same order as defined in the choiceLabels parameter. The choiceLabels argument cannot be null.

Using the choiceLayout parameter

  • For long labels, use the "STACKED" option for choiceLayout.
  • The "COMPACT" option for choiceLayout should only be used for radio buttons with short choice labels, such as "Yes", "No", or "Maybe". When using the "COMPACT" option, labels with text longer than two lines will be truncated.
