i realize that there is no FirstHeaderRenderer on GroupedList, but is there a way to simulate that?
I am using a GroupedList with blank Headers as a neat way to organize some items, but the first Header feels like a waste of screen estate.
You can use setHeaderRendererFactoryWithID() to register multiple header factories.
Then, you can use headerFactoryIDFunction to tell the GroupedList to use a particular factory of the first header only.
Thanks so much.
