Hi,

The arrange options cannot be chosen by the end user in the diagram. By default, the arrange all will perform the layout found by the sirius DefaultLayoutProvider: see https://www.eclipse.org/sirius/doc/developer/extensions-provide_custom-arrange-all.html.
You can provide your own tabbar action (see https://www.eclipse.org/sirius/doc/developer/extensions-provide_tabbar_extensions.html) to execute a specific arrange algorithm. The new action can call org.eclipse.sirius.diagram.ui.tools.internal.layout.provider.CompositeTopDownProvider.getLayoutNodeProvider(IGraphicalEditPart) for instance, and then execute the command returned by org.eclipse.gmf.runtime.diagram.ui.services.layout.AbstractLayoutEditPartProvider.layoutEditParts(List, IAdaptable)

regards,

Florian
