I've tried the new API menu.
On menus other than the admin area, the group type menu can be set to expand and collapse properly.
But on the adminarea menu, the expand and collapse feature doesn't work.
How do I make modifications to the menu on the "adminarea" page so that it can collapse the same as other public pages?
Thank you.
