title: Change the number of displayed products in Prestashop
body: <p>I have developed a Prestashop online store with a custom template.</p>
  
  <p>Now, everything is OK, but the category product listing. I'm showing rows of three products, so, when showing the default pagination of 10 products per page, last row has only 1 product.</p>
  
  <p>I cannot find how to change the pagination options so the user cannot choose the default values of 10,20 and 30 products per page and change them for 12,24,36 </p>
  
  <p>Thankyou in advance-</p>
