TOPIC: category position

Hi, I need to know if is possible to positionate the category icon on the left side instead on the top

Well, you will have to change the html and that is something I won't advise. More over the next version will look like this:
labs.compojoom.com/index.php/hotspots
and there I won't advise you to change the position of the categories when you don't know what you are doing.
