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.

BWidgets is a popular pure-Tcl widget set [in
Batteries Included distributions?] with an excellent combobox. [... List others, including

Description: Tcl/Tk 8.0 or better based, tcl only, combobox. All
the code is in one file, with an API similar to the standard
Tk widgets (with subcommands such as configure, cget, insert
etc). Emulates the look and feel of a Windows combobox.
Supports all platforms supported by Tcl 8.x. Recommended
used with Tcl 8.x. New versions continue to appear above -
check to see if a new release with bug fixes and features is
available.

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).
