Dropdown menu

I’m doing a menu with two levels of choices. When mouse is over the upper menu I want another menu to be shown underneath it. That’s no problem. But when i roll off the menu button and go down to the menu below, I want the undermenu to stay, but i can’t figure out how!
Please help =)
