This control will allow to display a cascading list items as a tree view and allows to select the list items and save the selected list items in the referred Share Point list. This control is intended to use in the custom list forms where a parent and child lists are referred as two look up columns.
With the existing look up columns in share point, the relation ship between parent and child look up columns is not enforced. The alternative approach for this is to use SP Services Cascade Drop Downs. The SP Services Cascade Drop Downs will not allow multiple selection of Parent look up column.
The cascaded tree view will allow the selection of multiple selection of parent -child look up columns.
