I created three Content Taxonomy CCK fields with a three-level vocabulary (province, district, subdistrict) with a tree display widget, selected to display collapsed. When each is a separate field everything behaves properly. When I move the three fields into a field group, they display in the submission form expanded and the role of the "+" and "-" tree controls are reversed.

mh86 commentedyes, that's a bit strange behaviour. somehow jquery.hide() doesn't work if the content is already hidden. the problem has to be fixed in the Taxonomy Manager module

janec commentedMaybe not the solution you are looking for but when I added the following to the theme's CSS it seemed to work quite well.
li.expandable ul.treeview, li.lastExpandable ul.treeview{
display: none;
}
Then I put each tree in a collapsed field group so that things start a bit more compact.
