Can you explain more clearly?

as you can see in the image above, there is no function in properties like adding collection and something like that, so cause that i have to add it manually with code, and adding manually is annoying and confused for sub items, i was trying to make like this image in below with DarkTreeView, but i can't

The default node editor isn't compatible with darkui because it uses custom code instead of the in-built dotnet node classes. Adding a custom property editor is a pain in the ass so I never bothered - all the UIs I created with darkui were built programmatically so it wasn't worth the time investment

You can either follow the example and add the nodes through code, or you can extend darkui to have a custom editor.
