• Automatic Resizing and Minimization - Telerik WPF RibbonBar and its composite parts fully support automatic resizing.

The Telerik RibbonBar also supports minimization that allows you to hide the RibbonBar and let only the tabs appear, thus saving space. Clicking a tab will make the RibbonBar popup and let you use all its controls.

All RibbonBar galleries and pop-ups mimic Office galleries exactly and fully comply with the ribbon UI requirements. Telerik RibbonBar allows you to fully control the pop-ups’ location, size and content. The RibbonBar’s ColorPicker galleries provide an advanced implementation for color selection. Read more
