Moving Items From Multiple Sortable Lists

Moving Items From Multiple Sortable Lists


With the JQuery UI sortable list you can move items from one list to
another, as long as the list your moving it to is not empty. An
example of this can be seen at http://ui.jquery.com/functional_demos/#ui.sortable
Basically if you move all items to one list, then try moving them back
you will not be able to do so, because there is no place to drop it
into without other items already in the list.
This is something I would like to see fixed! Are there any work-a-
rounds for this problem?
