Module for Prestashop

We need a small & simple Module for Prestashop. This Job goes out ONLY if you know the module routine in Prestashop and if you know the system inside/out. Problem: Prestashop always uses a standard attribute for a product. That is unhandy, for example with Shoes -> always have a standard size already selected leads to wrong orders cause customers forget to choose their correct size. There are 3 types to set up an attribute: Drop Down field, Color field, radio Button Todo: - Module to install through the Prestashop Modules Routine. - Module hast to set "Please choose" as default (in DropDown fields) - Module hast to set color an empty/unselected as default (for color f ields) - Module hast to set the radio-buttons unselected as default (for radio button fields) - Module has to grey-out the "Add to cart" until an existing attribute is selected, if the product has more than one attribute, all attributes have to be choosen. Thats is it - feel free to ask
