ActiveBPEL® Designer User’s Guide
You can preserve Process Editor real estate by collapsing the container activities. The container activities are Sequence, If, While, Pick, Flow, Scope, Repeat Until, and For Each. They are listed in the Container palette.
To collapse a container, such as a scope, select the container, and select Collapse from the right-mouse menu. The small icon, illustrated in the collapsed scope below, indicates the container is collapsed. To expand a container, select it and select Expand from the right-mouse menu.
