title: Opencart list categories inside manufacturers
body: <p>I have searched for hours but could not find an answer to this, or a module to help.</p>
  
  <p>We are building a store and our client needs the ability to navigate the store by manufacturer. Is there any way that the manufacturer page can list the categories and subcategories.</p>
  
  <p>There seems two ways to do it.</p>
  
  <ol>
  <li>Add brands while adding categories in admin section.</li>
  <li>Get all categories inside the brands by join operation while viewing the manufacturer.</li>
  </ol>
  
  <p>Are there any modules available to link up categories with manufacturers so that I can display categories inside the manufacturer page.</p>
  
  <p>Or the only way is to query all the products inside the manufacturer and get the categories out of it... I guess it is not a good solution.</p>
  
  <p>So any suggestions would be a great help.</p>
  
  <p>Thanks.</p>
