How do I use jQuery to animate a drop menu?

Hi all.

I am new to scripting and I'm trying to avoid using Flash for this because it is quite simple... I want to animate an existing CSS drop menu, here's the test site . I need the sub-menu to slide out nicely below, and I'd also like to fade the hover effect on all the links in the menu.

I know this can be done with a small piece of code but I wouldn't know where to start, also I'm not sure how to slip it in amongst my existing script... Which, by the way, I would be glad to find a lightweight replacement for! I used a bulky chunk of JS to fade-in the entire homepage.

Thanks, RM
