Multiple Dropdown Component


a!multipleDropdownField( label, instructions, required, disabled, placeholder, choiceLabels, choiceValues, value, validations, saveInto, validationGroup, requiredMessage, labelPosition, helpTooltip, accessibilityText, showWhen, searchDisplay )

Displays a list of choices for the user to select multiple items and saves values based on the selected choices.

If users should only select one choice, use radio buttons or a dropdown component instead.

If there aren't many choices and users would benefit from easily seeing them all at once, consider using checkboxes.


Name Keyword Types Description




Text to display as the field label.




Supplemental text about this field.




Determines if a value is required to submit the form. Default: false.




Determines if the field should display as potentially editable but grayed out. Default: false.




Text to display in the field when it is empty.

Choice Labels


List of Text String

Array of options for the user to select.

Choice Values


List of Variant

Array of values associated with the available choices.

Selected Values


List of Variant

Values of choices to display as selected.



List of Text String

Validation errors to display below the field when the value is not null.

Save Selection To


List of Save

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

Validation Group



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



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

Label Position



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



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



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




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



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 choiceLabels and choiceValues parameters

  • The Choice Labels list and Choice Values list must be the same length.
  • Choice Values cannot contain nulls or duplicate values.
  • Choices display in the same order as defined in the Choice Labels parameter. The Choice Labels argument cannot be null.

Selecting, saving, and clearing values

  • If a single item is selected, the system saves a single-item array.
  • 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.
  • If you are trying to decide whether to use a dropdown with search or a picker component, keep in mind that the dropdown search runs client-side and the performance cost of loading options happens on initial load whereas the picker search runs server-side and the performance cost of loading options happens while the user is searching. For small sets of options, we recommend using the dropdown component.


Use the interactive editor below to test out your code:

Multiple dropdown with the first choice selected by default and search on auto

Since the searchDisplay parameter is set to AUTO and the number of choiceValues is less than 12, no search box will be displayed.

Since the searchDisplay parameter is set to AUTO and the number of choiceValues is more than 11, a search box will be displayed.

Since the searchDisplay parameter is set to ON, even though the number of choiceValues is less than 12, a search box will be displayed.
