Flow layout is useful when you want to quickly add a lot of nested elements without relationships into a container (e.g. nested packages in UML package diagram - after setting the flow layout, you can easily add subpackages to a package and they will be automatically aligned).
All nested elements are ordered by their z-order. So you can reorder them using the order buttons Bring to Front, Send to Back, Back One, Forward One or using key shortcuts: CTRL+PgUp/PgDown.
Flow layout can be set one of this ways:
- right click on a container element and choose Container Layout/Flow.
- select a container element and in ribbon, open Format tab from Element context tab group - click on Container Layout button (in Layout group) and choose Flow from the drop down list.
