I’m trying many ways to create the trees diagram that is similar (GoJS Tree View) but I would like to add two trees diagrams, the first is arranged in the left side and the another once is arranged in the right side.
Could u suggest or give the example to solve my problem?
Well, the easiest solution would be to use two separate Diagrams. But I suspect that you want to do more than that. What do you actually want to accomplish?
