newbie** - can display more than 1 category column

Sorry I am new to Hikashop and cannot get my category display page to show more than one column across

Would like it to display three but don't know where to find how to change it.

see master.shopcen.co/index.php/categories/category

found what it was with a bit more digging here on the forum.

bootstrap was 'on' - which was making all listings vertical and singular.

Turning this off solved this issue

under general display options there is the ability to turn bootstrap on or off
