CMS Made Simple Forums

I was wondering if it is possible to make the horizontal CSSmenu that is integrated with CMSMS expand upwards. As all normal menu's do, it goes down when you mouse over the parent item. For this site I'm making it would be usefull to let it go up.

The menu will only be one level deep, so the code doesn't need to be changed for deeper levels.

I'm keeping my fingers crossed, hoping this is possible.

THNX in advance
