Using the TreeView style

The TreeView presentation style provides an easy way to create DataWindow objects that display hierarchical data in a TreeView, where the rows are divided into groups that can be expanded and collapsed. Icons (+ or –) show whether the state of a group in the TreeView is expanded or collapsed, and lines connect parents and their children.

This TreeView style report groups by manager ID and state and lists employee information and salaries:

The sample for TreeView presentation style shows a tree view with department head ID at the top level. Some nodes are expanded to show states at the next level, cities at the third level, and details for individual employees in each city.
