Checkbox By Index Component Share Share via LinkedIn Reddit Email Copy Link Print On This Page Function a!checkboxFieldByIndex( label, instructions, required, disabled, choiceLabels, value, validations, saveInto, validationGroup, requiredMessage, align, labelPosition, helpTooltip, choiceLayout, accessibilityText, showWhen, choiceStyle ) Displays a limited set of choices from which the user may select none, one, or many items and saves the indices of the selected choices. To save a value instead of an index, use checkboxes. This component is not available from the interface component picker in the design view. 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 List of Number (Integer) Indices of choices 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 indexes when the user changes the selections. 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. Alignment align Text Determines alignment of choice labels. Appian recommends this setting only be used inside the Grid Layout component. Valid values: "LEFT", "CENTER", "RIGHT". 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. 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". Choice Layout choiceLayout Text Determines the layout. Valid values include "STACKED" (default) to display the choices one on top of another and "COMPACT" to display the choices side-by-side. 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 Saving values If a single item is selected, the system saves a single-item array. If no selection is made, the system saves a null value into the component's saveInto parameter. If a single item is selected, the system saves a single-item array. Using the choiceLabels and choiceLayout parameters Choices display in the same order as defined in the choiceLabels parameter. The choiceLabels argument cannot be null. The "COMPACT" option for choiceLayout should only be used for checkboxes 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. For long labels, use the "STACKED" option for choiceLayout.
