List categories vertically instead of horizontally

[leeanthonyattard]

Hi All

On front page of the directory, where all the categories are listed. Right now they are being displayed in 3 columns alphabetically from left to right (horizontally). I need them to be displayed in 3 columns alphabetically from top to bottom (vertically).

Is there any way to do this? cant seem to find an option in the backend.

If there isn't an option is there a modification I can do to one of the files to get it to work this way?

Many thanks
Lee
