Chained Selects lets you "chain" multiple select lists together so that the selection in a "parent" list can tailor the options available in a "child" list. Chained Selects supports unlimited unlimited number of "chains" in in a form.

In order to Create a chain select list you have to use the SQL Form Field and the fields will be loaded using AJAX JSON Calls.

The first option of a Chain select list can also be a Radio list.
