Ribbon panels organize commands and controls on the ribbon.

You use rows, sub-panels, and drop-downs on a ribbon panel to organize the commands and controls you want to display on the ribbon. Each panel is divided into two halves with a panel separator; an upper and lower half. Rows above the panel separator are displayed by default while those below it are displayed only when the panel is expanded. Each panel can also be assigned a command to its Panel Launcher button, which can be used to start an associated dialog box. For more information about ribbon panel customization, see Ribbon Panels.
