title: Magento dropdownattribute with existing products for webshopowner to fill out
body: <p>Manage Options</p>
  
  <p>Hello,</p>
  
  <p>I was wondering if it's possible for magento to display the current products in a dropdown menu for the shopowner to select as an attribute value.</p>
  
  <p>For instance I've made a customattribute called engine for a product(car) and I want him to be able to select wich engine the car has from the engines he already put into the system.</p>
  
  <p>ADMIN: Catalog → Attributes → Manage Attributes → New Attribute</p>
  
  <p>Then make a dropdown menu, then to be able to select existing products as a value for the attribute.</p>
  
  <p>Hopefully this is clear enough.</p>
