Using "Mansonry Galerie" content element for posts (not as a picture galerie)

Hello Dear Kriesi Team,
i just came across a challenge when using the importet “freelancer demo”, It shoes a nice mansonry galerie in the second section of the home page. I tried to place some posts from the blog there in the first column. But the mansonry galerie style only seems to be available for pictures.

My question:
How can i display the mansonry galerie with posts from a certain category?

(I already tried the magazin grid and post element, but they don’t have a very nice layout that would go well with the theme)

Many thanks!
Johannes
