this is very difficult task

add different class to each div and add float and height to each class
i suppose fixed height won't be good for all forum sections but I doubt you can do anything more without javascript...

When i want to change the way of the categories are displayed at press of the button in section home page.It display the all categories are listed on the page in one column.I have searched the mod main menu. php and frontend .php for the code and layout the section of the page and categories are set.
