Needing some xml + actionscript guidance/suggestions

Hey there!

I’m in the mist of a flash project and my client really liked how the (www.nike.com) navigation on this site works to get you into their multitude of sites. I don’t care about the sliding and following the mouse. I only care about the showing of “submenus” they way they are doing it to the side with the easing and reveal effects.

I would like to create the navigation effect with XML and Actionscript 2.0.

Anyone have any suggestions or places I could go to learn how to do the above technique?

Thanks for any help in advance.
