Sortable nested solution?

Sortable nested solution?


I was reviewing the forum for a solution on using the jQuery UI
sortable for nested lists. Just briefly, items that are sorted out of
the nested list no longer can be inserted as child elements of top
elements.
Reference:

Does anyone have a way of solving the problem as described in the
previous thread?
