The WPF Ribbon provides an application UI similar to Microsoft Office UI with an application menu and a backstage view. It provides features like serialization, keyboard accessibility, ribbon customization, and a mini-toolbar.
The quick access toolbar (QAT) is used to render frequently used ribbon items at the top-left corner of a window for easy access. Users can choose to place it above or below the ribbon.
WPF Ribbon control supports multiple contextual tab groups that can be hidden or shown in certain contexts.
In a multiple-document interface (MDI), parent and child forms have their own ribbon menus. Users can switch forms or merge them to combine ribbon menus and items within the parent form as needed.
Backstage is a separate view with tabs and buttons, displaying an application's information and basic settings. The backstage items can be positioned at the top or bottom of the view for easy access.
