Combination Box (Control) — Reference
Description
A combination box is a combination text-list control in which
both the text field and the list box are displayed permanently and
in which the text field can be used for text entry. Figure 6 “Combination Box” is an example
of a combination box.
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.
