A little help?

Hey just been working on my gaming site and saw this plugin, it is beautiful, thank you so much!

I’m having a bit of difficulty, you can see on this page: http://xinogamez.com/steam-library/

They are just vertical, I want to be able to see them like in your screenshot images, its just that I cant find the actual settings anywhere.

Any help would be greatly appreciated. thanks again!
