Ribbon Bars

Within a RibbonTab RibbonBars are used to group the RibbonButtons. This lets you create another level of categorization of your commands to make it easy for your end-users to find the commands they are looking for.

There is also a special "SplitButton" kind of RibbonButton which the user can use in 2 ways: Click on the button part to invoke a "default command" or click on the drop down portion to select a command from a list of commands displayed in the dropdown.

RibbonBar also has the ability to show a scrollbar button to scroll the contents horizontally when the width of the control becomes too low.
