One of the Office application design guidelines is that users should always have control of the Office application UI. To add this capability for the actions panes, you can add buttons that show and hide each actions pane from a custom tab on the Ribbon. To create a custom tab, add a Ribbon (Visual Designer) item to the project. The designer helps you add and position controls, set control properties, and handle control events.
To create a custom tab
On the Project menu, click Add New Item.
In the Add New Item dialog box, select Ribbon (Visual Designer).
Change the name of the new Ribbon to MyRibbon, and click Add.
The MyRibbon.cs or MyRibbon.vb file opens in the Ribbon Designer and displays a default tab and group.
In the Ribbon Designer, click group1.
In the Properties window, set Label to Actions Pane Manager.
From the Office Ribbon Controls tab of the Toolbox, drag a button onto group1.
Click button1 to select it.
In the Properties window, set Label to Show Actions Pane 1.
Add a second button to group1, and set the Label property to Show Actions Pane 2.
From the Office Ribbon Controls tab of the Toolbox, drag a ToggleButton control onto group1.
Set the Label property to Hide Actions Pane.
