To take advantage of the latest features and improvements, we always recommend you use the latest version whenever possible. See the latest version's page for information about what's been changed. Multiple dropdown Function: a!multipleDropdownField_20r2() Displays a long list of choices from which the user may select none, one, or many items and saves values based on the selected choices. To save the index instead of a value, use multiple dropdown by index. If the choice is exclusive, then consider using radio buttons or a dropdown component. If there aren't many choices, consider using checkboxes. 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. 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. Choice Values choiceValues List of Variant Array of values associated with the available choices. Display Value value List of Variant Values 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 values when the user changes the selections.

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. 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. Notes If you set Label Position to "ADJACENT" or "ABOVE", but do not give a value for Label, a space still displays to the left-side or above, respectively, of the component as if there was a label displayed. To ensure the component appears to the far left when Label has no value, use "COLLAPSED" for Label Position. Choices display in the same order as defined in the Choice Labels parameter. The Choice Labels argument cannot be null. 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 Save Selection To field. If a single item is selected, the system saves a single-item array. Choice Labels and Choice Values must be the same length. Choice Values cannot contain nulls or duplicate values.
