The DevExpress Accordion for WPF is a feature-rich navigation control designed to address a wide range of navigation-related use case scenarios. You can create advanced hierarchical navigation menus with unlimited nested navigation elements, categorize elements into groups, filter out items based on text searches, and auto-populate the WPF Office navigation bar with groups.
The DevExpress WPF N**Bar control is supported as part of the Outlook 2013 and all previous versions of the Office UI, and its features include:
Navigation panel inspired by Microsoft Outlook.
The sidebar is inspired by Microsoft Office 97
Windows Explorer inspired by Windows File Explorer.
End-user customization.
Auto-hide.

DevExpress Tilen**pane is designed to sit at the top of the application window (like a ribbon) and can be thought of as a touch-friendly version of the traditional navigation elements used in Windows desktops or touch-enabled hybrid applications.

The DevExpress WPF Wizard control allows you to build wizards with great looks and pixel-perfect element layouts, eliminating the need to deal with time-consuming issues such as the ones described above. To put it simply, you drop the WPF wizard control and instantly convert the form into a multi-page wizard, only having to worry about the actual page content and implementing your own navigation logic if needed.
