title: Configurable product
body: <p>I'm playing with custom module shoppingcart.
  I currently have a product part with fields price and sku. What would be the best way to add a configurable product for example a shirt has different colors and sizes. But now all products has to be configurable. I want to have the user select from a dropdown in my view from available sizes.</p>
  
  <p>If I create a new content part and attach enumeration field to i must choose one item when i create product from backend. What I want is to render all the items in the enumeration field in the view and be able to select one.</p>
