GtkExpander does have a little control (an arrow) associated with it that 
normally the user would click to expand the expander. Not sure if you want that.

Generally speaking if you want some container to automatically apear when 
selecting a list item, you can either use the expander and connect the signal 
for list item selected (don't remember what it is) directly to the expander (or 
to a function which calls a function on the expander to expand it), or, if 
you're not using GtkExpander, accept that signal and just 
show/hide/insert/create/whatever your new widget.
