Radio Button By Index Component Share Share via LinkedIn Reddit Email Copy Link Print On This Page Function a!radioButtonFieldByIndex( label, instructions, required, disabled, choiceLabels, value, validations, saveInto, validationGroup, requiredMessage, labelPosition, choiceLayout, helpTooltip, accessibilityText, showWhen, choiceStyle ) Displays a limited set of choices from which the user must select one item and saves the index of the selected choice. To save a value instead of the index, use radio buttons. Parameters Name Keyword Types Description Label label Text Text to display as the field label. Instructions instructions Text Supplemental text about this field. Required required Boolean Determines if a value is required to submit the form. Default: false. Disabled disabled Boolean Determines if the field should display as potentially editable but grayed out. Default: false. Choice Labels choiceLabels List of Text String Array of options for the user to select. Display Value value Number (Integer) Index of the choice to display as selected. Validations validations List of Text String Validation errors to display below the field when the value is not null. Save Input To saveInto List of Save 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: Configure Buttons with Conditional Requiredness Validation Groups for Buttons with Multiple Validation Rules' 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 helpTooltip 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. Feature compatibility The table below lists this component's compatibility with various features in Appian.
