Magento configurable product problem

Magento forums all so full of questions so I have better chance to get answer here than there.

So I’m fairly new with Magento and I have problems in creating configurable product. When I’m trying create it, all my options appears in to grey box (example): http://demo.knarsku.com/magento/electronics/computers/build-your-own/my-computer.html althought I want that they look like this (example): http://demo.knarsku.com/magento/zolof-the-rock-and-roll-destroyer-lol-cat-t-shirt.html .

So any ideas what I’m doing wrong? I have read many tutorials but I can’t never get the end result I want.

I’ve also tried to make Simple product with custom options but it will look exactly the same
