About list sources

List boxes, drop-down lists, combo boxes, and grid columns allow users to select data from a displayed list. The source of the data that is presented in this list is called the component's list source. The specifications for a list source determine what items show in the component's list.

A list source can be any of these types:

Inline
IDO Collection
IDO Method
Script

Users can also specify a list defined using the User Defined Types form.
