Table Overview of the Layout Hierarchy 
The following table overviews present a more detailed description of the layout hierarchy for iViews and Web applications. Red cells explicitly prohibit certain nestings. Yellow cells indicate cases where elements can be placed into other elements with certain restrictions only (see also the reasons for these rules).

*) As iViews are simple applications, tabstrips and table views should not be placed into group controls.
Red cells: Nesting forbidden
Yellow cells: Nesting allowed under certain conditions only
