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).

iView

Element below can be placed within Container to the right	Container
Element below can be placed within Container to the right	iView (Tray)	Tabstrip	Group	Subgroup
Tabstrip	yes: together with other elements no: as single element	no	no *	no
Group	yes: together with other elements no: as single element	yes	possible - but use with care! one level at maximum - use different types for the nesting	no
Subgroup	yes	yes	yes	no
Table View	yes: together with other elements no: as single element	yes	no *	no
Text Area, Graphic	yes	yes	yes	no
Separator (White Space, Line)	yes	yes	yes	no
Heading	yes: for subgroup, text area, graphic	yes: subgroup, text area, graphic	yes: subgroup, text area, graphic	yes (as heading for the subgroup)
Field, Selection Element, Icon, Button	yes	yes	yes	yes

Legend

· *) 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

· The bold no's indicate common errors, such as nested tabstrips.
