NestedSortable and Draggable

Hi
I would like to use the same thing as in the draggable/sortable demo :
http://jqueryui.com/draggable/#sortable

but with nested sortable
https://github.com/mjsarfatti/nestedSortable

both works well but I can't add the draggable element into the nestedSortable list and do it also sortable. Can someone help me with this please?
Thanks
