Help on jquery navigation plugin

Hi all,

I need help with jquery navigation plugin ( https://github.com/dansdom/plugins-navigation ) by Daniel Thomson. Its a  wonderful tool and I modified it to an extent where it suits my requirements.

But how can I do these two things,

A. I have positioned it at the bottom of the screen and I want the submenus to shot up and not drop down when the mouse hovers over it.

B. Can each menu calculate its width and take that much space? I did this by creating separate ul ids for each but is this the only way?

I am rather new to javascript and jquery, so any help would be much appreciated.

Thanks and regards,

RKD.
