For default library not support multiple select. You can see here some solutions:

• https://github.com/jerosoler/Drawflow/issues/322
• https://github.com/jerosoler/Drawflow/issues/50

To be able to do it you need to detect the collisions, it can be achieved with this method: https://developer.mozilla.org/en-US/docs/Games/Techniques/2D_collision_detection

You just have to have the sizes of the drawn box and the size of your nodes.
