title: Wordpress show posts from children terms of a taxonomy term
body: <p>I have a a custom taxonomy called "products_cat" this custom taxonomy has different terms as parent categories: "Electronics", "Computer", "Home Appliances", etc. And then under each of those terms I have more sub-terms like under "Electronics" for example I have "TV", "Audio", "Home Theaters", "MP3",etc.</p>
  
  <p>So the thing I'm trying to do is to have within the taxonomy-product_cat.php a code that display the current chosen Taxonomy (suppose Electronics) and then have the titles of all children and the products under each one of those.</p>
  
  <p>Thanks.</p>
