title: Magento - get a parent category and all sub-sub-categories
body: <p>I have a single category, that has 2 subcategories. Within each of these categories, are 5 subcategories.</p>
  
  <p>Is there a way to get a list of all of these 10 sub-sub-categories?</p>
  
  <p>Thanks </p>
  
  <p>EDIT:</p>
  
  <p>Something like this:</p>
  
  <pre><code>  Main Category
         Sub_Cat_1
              Cat_1
              Cat_2
              Cat_3
         Sub_Cat_2
              Cat_4
              Cat_5
              Cat_6
  
    Wanting output like:
  
    Cat_1
    Cat_2
    Cat_3
    Cat_4
    Cat_5
    Cat_6
  </code></pre>
