Epics, can you implement user setup for created UMG widgets category? It loos like it si possible to do from C++ code, but not for UMG created widgets.
After looking over your request above, I have written up a request (UE-31657) and I have submitted to the developers for further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your time and information.
Creating categories for widgets is already supported. Select the top node in the widget tree (the CDO) and there’s a category box at the top of the details panel.
