How can the DevExpress menu appear in the title bar of a WPF window, for example below?

Right now I have a main menu attached to the window, but I would like to move it to the window title
<dxb:BarManager CreateStandardLayout="True"> <dxb:BarManager.Bars> <dxb:Bar IsMainMenu="True" UseWholeRow="True"> <dxb:Bar.DockInfo> <dxb:BarDockInfo ContainerType="Top" /> </dxb:Bar.DockInfo> </dxb:Bar> </dxb:BarManager.Bars> </dxb:BarManager>
