Please help me moving my Menu UP instead of down

 Hi people,

I'm working on a menu that's going up. But i can't figure it out how to go make the LI going up. My menu structure look likes this:

<ul>
        <li>menu 1</a>
                <li><a href="some link">sub1 of menu1</a></li>
                <li><a href="some link">sub2 of menu1</a></li>
        </li>
        <li>menu 2
                 <li><a href="some link">sub1 of menu2</a></li>
                 <li><a href="some link">sub2 of menu2</a></li>
                 <li><a href="some link">sub3 of menu2</a></li>
                 <li><a href="some link">sub4 of menu2</a></li>
        </li>
</ul>










When there is a mouse over on menu1 or menu2 it should move up until the lost submenu. For an example (it's in flash) but it's the exact way i wanted: www.skydiveanhwere.nl Every li is in my css 25px high.


Someone having a solution for this?


Thnks in advance and sorry for my poor English
