Hi, I've been trying to learn how to make a node editor tool in unity but I'd like to try it in UI Elements. I think GUILayout.Window is a pretty good solution and drag feature comes out of the box. There is a good sample here: https://docs.unity3d.com/ScriptReference/EditorWindow.BeginWindows.html UI Elements do have a similar feature in examples in github repo. I noticed that in this sample have a similar window element but it fills in its container. I couldn't find any solution to make similar behavior like GUILayout.Window. Also, I've tried to dig in this repo for graph editor like node editor. But it's beyond complicated and huge project. Thanks in advance!
