New structure for subforum
 

I would like a subforum like this:
https://vborg.vbsupport.ru/external/2014/08/3.jpg
then in two columns and the column without LAST MESSAGE.
Can you tell me how to do? More or less I understand that I must act on a variable, but as this is only one, inserting it appears obvious, in a single row with 6 cells. And this is a problem because some of my subforum comosti are more than 15 sub-sections, and then ccreerebbe a single row with 15 cells: S
but I would like to divide them into two main columns, you know help me?

You would have to edit the forumhome_forumbit_level1_post template and put a condition around it so that it only shows that way on the forumdisplay pages. Then you can use CSS to have two columns (and again, put conditions around it to only be that way on your forumdisplay pages). [HOW TO - vB4] Two column forum/sub-forum setup via CSS only
