A combo box is a commonly-used GUI widget. It is a combination of a drop-down 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. An example of this use is the address bar of graphical web browsers.
[edit] Terminology
The term "combo box" is sometimes used to mean the same thing as "drop-down list," owing to the variability of terms. This usage is likely the result of Visual Basic, and later the Visual Studio suite using the term "combo box" for both types of control.
This distinction between "combo box" and "drop down list" is sometimes clarified with terms such as "non-editable combo box" (or something similar). Alternatively, some apply the term "combo box" only to controls that allow edits.
