jquery sortable nested list

[eluser]threestate[/eluser]
I've searched all over, but with no luck.
does anybody have an example of how to do jquery sortable nested lists?
i want to create a menu sorter in my admin area

the fields i have are
id (int)
name (varchar)
parent (int)
sort (int)

the parent list item has a 0 in the parent field (as it isnt a child li)
and child list items have the corresponding parents id number

i found how to do it with a one dimensional list (and post back to the db using scriptaculous)
but i need to do at least a two dimensional list.
any thoughts or links to tutorials would be appreciated

thanks
