Treelist 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. Treelist 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. Treelist supports Office 365 Icons and SVG Icons. You are purchasing version 4.3 featuring Skeleton, my new, quick click Professional Light Themes that can be used on normal Treelists and Treelists which have a Base Node as their starting point and TreeStructure - the ability to maintain a Sorted Parent->Child 2 Column list that can be loaded directly into the TreeList Sheet
