How to let Nodes be movable?

Thank you.

I think other people would prefer if you entered text in your questions, rather than embedding the text in the image. Using normal text entry permits people to search for particular topics.

In this case, you are talking about the Drag Drop Fields sample, Your question is how to make the nodes movable or copyable or deletable.

The easiest answer is to look at the implementation of that sample. Notice how the node template sets these properties:

          { movable: false,
            copyable: false,
            deletable: false },

In 1.6 (but not in 1.5) we have improved the sample so that you can change those values, or even just delete all of them to get the default true values. So I suggest you start with the sample code at

Thank you. I worked it out.
