title: Product Categorization, Viewing and adding to Menu in Drupal 7
body: <p>I'm searching for ideas to do the following in Drupal-7:</p>
  
  <p>1- Create <strong>product categories</strong> (Main category, and sub categories, and products itself...)</p>
  
  <p>ex. <strong>Cars</strong>, Motor Cycles ... are Main categories of products,
      Audi, Toyota ... are subcategories of a <strong>Cars</strong> main category,
      Audi A8 ... is the corresponding product.</p>
  
  <p>2- <strong>Dynamically</strong> add the <strong>Main categories</strong> under a <strong>menu</strong> item.</p>
  
  <p>3- <strong>Main category</strong> item when clicked view a <strong>page of a related Sub-categories</strong>.</p>
  
  <p>4- <strong>Sub-Category</strong> item when clicked view a <strong>gallery of images of related products</strong>.</p>
  
  <p>I've tried to work with content types and "Node Reference", and view it conditionally using "Views", or working with Taxonomy. But I think I need to integrate those solutions all to reach what I really want.</p>
  
  <p>What steps should I follow using drupal modules, or <strong>Will it need a custom module?</strong></p>
  
  <p>Thanks in advance!</p>
