Is there a way to enable drag and drop sorting on a collection of OptionItems used in SelectionElementBlock?
There is an option to move up/down but that just moves it for one place, for a long list that takes time. Some sort of dragging is already implemented in default CollectionEditor, but when dragging an item from the list and dropping nothing changes.
Milos, unfortunately not. It's not possible, it's a missing feature and there's no workaround as of now. You have to use Move Up/Move Down commands.
