Screen Layout – Part II: Layout Hierarchy – Appendix

By Gerd Waloszek, SAP AG, Product Design Center – 04/18/2002, updated 06/07/2002

Example: Hypothetical Layout Hierarchy for Web Applications | Hypothetical Table Overview of the Layout Hierarchy for Web Applications

Back to article

This page presents a second example of a layout hierarchy for comparison with the iView layout hierarchy shown in the main article. It is a "hypothetical" layout hierarchy for Web applications – "hypothetical" because it does not exactly correspond to the current SAP Web application (IAC) guidelines. In addition, these guidelines are currently under revision, and it is open how such a hierarchy will look like for the new Web applications.

In the example below, I introduced the following difference to the current guidelines for Web applications: Simple elements and containers can be placed on the application background. This is similar to the header data in R/3 applications, which are also placed on the application background; R/3 applications, however, do not have the concept of an area. I allow that elements can be placed on the application background for didactic reasons, because I want to present a more complex layout hierarchy.

 

Example: Hypothetical Layout Hierarchy for Web Applications

The major differences to the iView layout hierarchy are: (1) Web applications offer areas as "large-scale" containers, (2) in Web applications nesting may be deeper in some cases than for iViews because they can become more complex than iViews.

• Application Background = Window/frame background = application container – may contain:
  • Area – may contain:
    • Tabstrip – may contain:
      • Group (if it is not the only element)
      • Subgroup
      • Table View (if it is not the only element)
      • Simple elements
      • Separators
    • Group – may contain:
      • Tabstrip (if it is not the only element)
      • Group (if it is not the only element, different group types only)
      • Subgroup
      • Table View (if it is not the only element)
      • Simple elements
      • Separators
    • Subgroup – may contain:
      • Simple elements
      • Separators
    • Table
    • Simple elements
    • Separators
  • Same as area

Note: This layout hierarchy does not exactly correspond to the current SAP guidelines for Web applications (IACs) because it allows elements to be placed on the application background.

 

Hypothetical Table Overview of the Layout Hierarchy for Web Applications

The following table overview provides a more detailed description of the layout hierarchy for Web applications. Red cells explicitly prohibit certain nesting. Yellow cells indicate cases where elements can be placed into other elements with certain restrictions only.

Element below can be placed within Container to the right	Container
	Application (Background)	Area	Tabstrip	Group	Subgroup
Tabstrip	yes	yes (can be a single element with area header as title)	no	yes: together with other elements no: as single element	no
Group	yes	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	yes	no
Table View	yes	yes	yes	yes: together with other elements no: as single element	no
Text Area, Graphic	yes	yes	yes	yes	no
Separator (White Space, Line)	yes	yes	yes	yes	no
Heading	yes	yes: group, text area, graphic	yes: subgroup, text area, graphic	yes: subgroup, text area, graphic	yes
Button	yes	yes	yes	yes	yes
Field, Selection Element, Icon	yes	yes: Header data, group no: other data	yes	yes	yes

 

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

Note: The layout hierarchy on which this table overview is based does not exactly correspond to the current SAP guidelines for Web applications (IACs) because it allows elements to be placed on the application background.
