What is "combo box"

n. (context graphical user interface English) A GUI widget that is a combination of a dropdown list or list box and a single-line textbox, allowing the user either to type a value directly into the control or choose from the list of existing options.

A combo box is a commonly used graphical user interface widget (or control). Traditionally, it is a combination of a drop-down list or list box and a single-line editable textbox, allowing the user to either type a value directly or select a value from the list. The term "combo box" is sometimes used to mean "drop-down list". In both Java and .NET, "combo box" is not a synonym for "drop-down list". Definition of "drop down list" is sometimes clarified with terms such as "non-editable combo box" (or something similar) to distinguish it from "combo box".
