I am looking for a script, possibly supported with mootools, but not necessary, which would allow me to create a vertical menu. However, I want it of the type at http://www.aaronbirchphotography.com/ or http://www.apple.com/startpage/ (Latest in iTunes menu).

That is I am looking for something which is vertical and expands on a mouseOver. Any help would be greatly appreciated. I suppose if I can't find it, I'll have to write my own, but it would save me a lot of time if I don't have to.

Thanks for your time.
