I just reinstalled 10.04 and I can't for the life of me remember how I did this. I used to have an icon on my panel which, when clicked, would roll out a specific sub-menu found int he main menu.
For example: Whereas I can click Applications > System Tools > VirtualBox > Webserver right now, I used to e able to click the icon on the panel and the Virtualbox menu would pop up out of the icon. It wasn't a drawer because the items displayed were whatever was in the linked submenu, I did not have to update them both separately.
Any ideas how I got that working before?
It's pretty non-intuitive, but I remember figuring it out a few times, and I basically remember.
You right click on a menu item in the menu you want, and choose "Entire Menu", then "Add this as menu to panel".
