DevExpress WPF Accordion Control

DevExpress.Xpf.Accordion.AccordionControl is a hierarchical navigation control with an unlimited tree depth, multiple selection / expand modes, optional Office-style navigation-pane layout, built-in search, and Office Navigation Bar integration. It's the recommended replacement for the older NavBarControl in new projects — simpler API, more customization room, modern look.

When to Use This Skill

Use this skill when you need to:

• Add a hierarchical navigation sidebar to a WPF app
• Define items statically in XAML, or bind to a ViewModel collection
• Switch between Default (expand/collapse tree) and Navigation Pane (top-level items as tabs) view modes
• Show items with glyphs, headers, custom content (editors, images)
• Add a search field for end users to filter items
• Collapse the panel into a compact strip with glyph-only items
• Decide between AccordionControl, NavBarControl, and HamburgerMenu for navigation
