When to Use

Recommended
Provide a combination box when the user can either choose from a set of commonly used predefined items in the list box for replacing the contents of the text field or enter values into a text-entry field that are not in the list box.

Recommended
Do not use a combination box if the window in which the combination box is displayed is sized so that two items cannot be displayed in the list box. Instead, use a drop-down combination box.

Guidelines

Required
Do not allow the list box in a combination box to take focus.
