Is there a way to have a content browser like navigation where it is just a bunch folders and you just need to click to + and - icon to expand and contract the view?
You can see what I am after here:
Hi @bentraje, thanks for reaching out us.
Please have a look at the TreeViewCustomGUI class and to Adding a icon to a treeview field.
Finally you can get nice hints by searching for TreeView and have a look - although it's a C++ example - to the Layer Shader Browser example.
Thanks for the reference.
For anyone trying to achieve the same,
here is a sample file.
Thanks again for @zipit for the help.
