Multiple Dropdown By Index Component Share Share via LinkedIn Reddit Email Copy Link Print On This Page Function a!multipleDropdownFieldByIndex( label, labelPosition, instructions, required, disabled, placeholder, choiceLabels, value, validations, saveInto, validationGroup, requiredMessage, helpTooltip, accessibilityText, showWhen, searchDisplay ) Displays a list of choices for the user to select multiple items and saves the indices of the selected choices. To save a value instead of the index, use a multiple dropdown component. Parameters Name Keyword Types Description Label label Text Text to display as the field label. 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. 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. Placeholder placeholder Text Text to display in the field when it is empty. Choice Labels choiceLabels List of Text String Array of options for the user to select. Selected Indices 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 Selection 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. 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. Search Display searchDisplay Text Determines when a search box displays above the options. Valid values: "AUTO" (default), "ON", "OFF". When set to "AUTO", the search box displays if there are more than 11 options. Usage considerations Using the selectedIndices parameter The indices passed to the selectedIndices parameter display as selected by default. If null is passed to selectedIndices, none of the options are selected. However, if a list is passed to selectedIndices, it cannot contain a null value. Choice index numbers start at 1. Indices passed selectedIndices cannot be less than 1 or greater than the length of the choiceLabels array. If a single item is selected, the system saves a single-item array. Using the choiceLabels parameters Options display in the same order as defined in the choiceLabels parameter. The choiceLabels argument cannot be null. Saving and clearing values If no selection is made or the selection is cleared, the system saves a null value into the component's Save Selection To field. Users can always clear the value using the x icon on web or the Clear link on the mobile application.
