Implementing WPF GroupBar (Navigation Pane)

The GroupBar control implements a navigation pane similar to the Microsoft Outlook Bar. It hosts categorized collections of items and custom controls in expandable/collapsible sections. Supports multiple visual modes, data binding, drag-and-drop reordering, context menus, toolbars, and full theme support.
