How can I easily add support for drag and drop?
It should set the node to fixed with current location of where it dropped it.
It is important that rest of the nodes still uses the ‘force directed mode’ to position rest of the nodes in the graph automatically

I’ve played around a bit without success, and wondering if anyone is able to give me a quick example on how to add such support as explained above.

    Finally got it working after figuring out it is not ideal to fight with two “drag” listeners (your own, and force.drag) attached to the nodes!

    Much better to only have your own “drag”-listener and call tick() manually which is the key feature of getting the force graph to position the nodes for you on every new node position on the node your dragging.
