Dropdown select

Stores multiple options, only one selectable at a time. In forms behaves like radio select but appears as a dropdown. Enumeration property.

Radio select

Same as dropdown — one option selectable. In forms appears as radio buttons instead of a dropdown. On records, behaves identically to dropdown.
