[TYPO3-english] gridelements in 4.6

[Domi]

Hello

I just try out the new gridelements extension, which brings very nice 
DragnDrop feature for the content elements in the BE. I created some CE 
Layouts and was able including them into the page.
How do I adjust my CEs frontend rendering? there is no additional 
markup. Also the grid container and grid container columns in the tab 
extended are empty.

Does anybody has a working configuration of gridelements?

Thanks

Cheers Dominic
