When minimized, the contents of the selected RibbonTabItem (SelectedTab) will not be visible and the height of the XamRibbon will be decreased to show only the ApplicationMenu button, QuickAccessToolbar and the RibbonTabItems.
When a RibbonTabItem is clicked while the XamRibbon is minimized, the RibbonGroups that belong to the clicked tab are displayed in a popup window.
If the AllowMinimize property is set to true, the end user can change the minimized state of the XamRibbon using either the right click context menu or by pressing Ctrl-F1.
