I've got a horizontal menu (relative position) with vertical submenus. The design for the home page puts the horizontal main menu close to the bottom of the page. Because of this, I want the submenus to expand upward instead of downward. When submenus expand downward, they require a scroll bar, and depending on the size of the window, you might only be able to see a couple menu items. If the menu expands upward, the whole menu will be visible. This would be ideal.
Thanks,
