jquery menu in 19m2, possible to use like original example?

I have need of a menu pretty much exactly like the "flat menu" example at:

http://jquery-ui.googlecode.com/svn/branches/labs/fg-menu/index.html

It is unclear to me if the menu component in 19m2 supports that behavior. The "overlay context menu" example for 19m2 menu is similar, but puts the menu over to the side, instead of underneath.

Is there any way to use the 19m2 menu widget to get behavior where the menu expands underneath, instead of to the side? 

[In general, I'm also curious if the various other hieararchical and ipod-like behaviors demo'd in the original filamentgroup version are planned to eventually come to jquery-ui?  Perhaps I should just use the original filamentgroup version? ]

Thanks for any advice.
