I think when I needed this, I just used a regular Fl_Browser
and Fl_Input field. Any items that didn't match the search
made the non-matching items in the browser 'hidden'.
So in other words, all items were still in the browser at
all times.. you can just hide the ones that don't match,
instead of having to delete them.
When individual items were hidden, the entries that weren't
hidden all grouped together correctly after a redraw.
IIRC, this feature wasn't documented.. in fact, involved
accessing the internal FL_BLINE struct (defined in Fl_Browser.cxx)
and manipulating the NOTDISPLAYED bit of the FL_BLINE->flags value.
I don't remember if I simply grabbed the Fl_Browser code, and
re-diddled it to do what I needed, or if I was able to use
the public interface.
I think if you acquaint yourself with the Fl_Browser code,
you'll get it.
