Can anyone answer my question?

Is it possible to place a droplist within another droplist, so that when
I select an item in the first droplist a further droplist appears from
that item. Hope you understand my problem.

Many Thanks

Neil.

This has always been like this on the Mac. Droplist only generates an
event if the item of choice changes. Selecting the already selected item
does nothing. Kind of annoying, I agree.

Beware that until v6.1, the combobox did not work in modal widget
bases.

A combobox will be scrollable in some instances if the list extends
beyond the bounds of the parent base widget. It's also suggested in
the help documents that a comboox be used for new code over a droplist.
I don't know for sure if it will be scrollable under windows, as I've
only used it under Motif, but it's probably worth a shot.
