Gets or sets a value that indicates whether the drop-down for a RibbonTab is open.
Assembly: System.Windows.Controls.Ribbon (in System.Windows.Controls.Ribbon.dll)
When the IsMinimized property is true, the Quick Access Toolbar, Application Menu, and tab headers are shown, but the tab contents are put in a drop-down and are not shown by default. When a user selects a tab header, the drop-down for the tab is opened and its contents are shown. Selecting or deselecting the tab header toggles the property between true and false.
If the IsMinimized property is false, the property is also false.
