Missing Extension in Opencart

Hi

I was searching a extension in opencart but i think its missing. I want this

www.bestylish.com/men-shoes-casual-1

Take your mouse on the product, a frame will appear in which you can see the available sizes at the bottom of that frame.
Another example is
http://www.myntra.com/men-casual-shoes?nav_id=18

This extension is really important for clothing/shoes stores.

if no one chooses to add that extension, you won't get it in the store. You can always hire someone in the commercial forums to do it for you
