In constructing a user form, you can add a Multi-Select list control to make it possible for the application's users to select more than one value for a single field. These lists save time and ensure accuracy by supplying a list of valid values for an input field.
You can source a Multi-Select list control from a data page, clipboard page, or report definition.
In the application that you create, the list displays as an auto-complete list, similar to the To field in an email message.
The UI Gallery landing page contains a working example of this element. To display the gallery, click Designer Studio > User Interface > Gallery > UI elements.
