With certain field types that are set to unlimited you get an "Add another item" button that lets you create as many fields as you need. If you set a field with a Select List widget to unlimited it instead gives you a select list box that has ctrl click functionality for selecting multiple.
I want to know if there's a way to make a Select List widget that is set to unlimited instead show a regular select list, and an "Add another item" button that creates further select lists.
