I was able to get to a layout like what you posted while in the inspector, but when I try to find the location of each li.product or the ul.products I have trouble finding them.
Because I cannot find them, I have tried adding either height:100% and position:relative to both Jigoshop’s frontend.css and my site’s style.css but there is absolutely no effect.
Again, I’m not very experienced with this stuff, just enough to get by, so if I am missing something simple, I apologize.
Edited this just to say that occasionally, when the page takes a little time to load, you can sometimes see it in the correct layout for a split second. I don’t know if that changes anything but I figured adding as much info as possible couldn’t hurt
