JQuery Gridster stack direction

Hi, in this modified code of gridster

http://jsfiddle.net/maxgalbu/UfyjW/

how can i limit the amount of rows and have new items stack to the right...so instead of expanding the bottom, it expands to the right and items move to the right as if they were moving to the bottom in the above fiddle.

this is like the 5th forum ive posted too, it seems no one can answer this...

As we tell anyone using a 3rd party framework. Since we are not the developers of that framework, it would be nonsense for us to dive into such in-depth code. Please contact the developers.
