You are purchasing version 3.2. Tree List uses hierarchical data to create lists of Items in an Excel Worksheet that can expanded and collapsed at Parent Nodes. When the Nodes are expanded or collapsed any descendants that are already expanded or collapsed persist. The finished list can be copied into a new Workbook or an existing Project - all of the Code is generated in a self-contained "Template" Worksheet Code Module. Tree List can be used to create many kinds of lists, including a Hyperlink Index to other Worksheets or Web Pages, a T.O.C. or an Options / Settings list. Tree List is highly configurable
