Diagram

Containers

This demo shows the Diagram widget's capability to wrap shapes into containers. A container is a special shape with the following features:

  • a container can contain other shapes (including other containers),
  • a container is dragged with its content,
  • a container can be collapsed with a collapse button.

To wrap a shape, just drop it into a container.
