[Plugin: Posts per Cat] posts in columns?

Hello,

thank you for this great plugin. There is only 1 thing that i couldn’t find out..

I used your code and than get the posts from all the categories. There is an option in the backend: “exclude categories different from currently displayed on category archive and ignore first category rules on category archive”

When i use that, only the post from that category wil be shown. Only now the problem comes. It is all in 1 column. And right now/there, i need to get those posts in 2 or 3 columns.

Am i doing something wrong? Or isn’t that possible?

thank you very much
Jeroen
