I’m trying to find a solution to get over the problem at the ObjectField asset picker dialog, it list all of my object assets of the supplied type in a flat list. In my case the folder structure of the assets is important for identifying the right asset and a tree view and custom search behavior would be a much better option for my application.
Ideally I’d override the picker dialog with a custom editor window but I still want the asset drag and drop functionality.
Otherwise is there a way to build a custom editor Field that on the surface looks exact the same and can support the drag and drop behavior of an ObjectField while pulling up a custom dialog?
