The requested feature is not offered by RadEditor and this module is designed to be rendered only inside the Module docking zone
You can set the DockingZone of the module to Top or Bottom but they will be not rendered as expected so this is not a solution:
<telerik:EditorModule Name="RadEditorNodeInspector" dockingzone="Top" />
<telerik:EditorModule Name="RadEditorDomInspector" dockingzone="Left" />
