Does JQuery have a method to resemble this functionality?

Hi all!

I've known this script for a while: http://www.dhtmlgoodies.com/scripts/drag-drop-folder-tree/drag-drop-folder-tree.html, but since I'm hooked on getting everything to work with JQuery, and because the mentioned script is from 2006, I was wondering if there's a built in method to do something like this?

I've played with the JQuery UI sortable, but it really doesn't work all too well when using it for rearranging a website menu structure. I can't work out the logic of parent/child relationships for each menu level, and I end up dragging several items in one drag.

Any ideas?
