combobox
A combobox appears to be an entry box which has associated with it a series of possible values, along with a button (with a down arrow) that, when pressed, displays the various options that can be selected for the entry box.

RS: In Enhancing BWidget is demonstrated how to extend the behavior of BWidget's comboboxes, to add a history of previous input; or to make them look like a chooser (somehow like the tk_optionMenu, which also is a kind of combo, but looks kind of old-fashioned these days).
