Add products to our webpage cart

Hello everybody! Please take a look at our webpage cart: [login to view URL] When you press choosing one of the products some options (for that particular product) appear below (please try it). So, that cart is pretty old and we have lots of similar products to add. In order to do that we need to separate them in two categories: "labels" and "others". When a customer press in "labels" what you see now (plus a couple of new products) should be visible. And when you press "others" a new set of products (but similar to these) will appear. Options are pretty much the same for every product (icon, font and colors, basically... maybe one or two need an extra line). We like this design and we'd like to keep it, so you have to have that in mind when you add the new stuff (and if you could add the side images we have in all the rest of the page, that would be even better). Ok! So what I need you to do is to modify this html to add the things I need. I'll provide the pictures and everything else you need. Please, don't hesitate to ask questions if there's something not clear enough.
