New Post: Region inside Mainregion

Hi List,
i have as most of the users, left a NavigationRegion and then my MainRegion.
In one of my Moduls i need a TabControl inside the MainRegion. This TabControl should host a Region as well, so i can add UserControls to them.

The other Moduls can live with the MainRegion
So, is there any chance to implement this

Thanks
Peter
