hello,guys
I'm implement some functions like model manage system, similar with asset browser, but the data come from Remote DataBase，so this is some questions on my way。

1.is there any way to add a separator in the model of the two control, so I'can drag to resize,
like asset browser.
2.how to hide this title? It's seem useless
3.can embed the Dialog like asset browser?
thanks a lot!
