I would like to extend my activity diagram by surrounding it with a boundary group displayed with a dashed line stroke. Furthermore, boundary nodes should be able to be linked with an inner node. I tried to implement the logic above by using some of the principles in the BPMN editor template (itemArray, itemTemplate) but it is kind of restricting mainly for two reasons:
- Ideally the boundary nodes should be draggable across the boundary group.
- Linking the mail icon with an inner node is not properly displayed (the source of the link should be the icon and not the bottom of the boundary group)
