title: Show Multiple Values in Drop Down list, CakePHP
body: <p>I have a drop down list, which shows a list of 'Product Categories'</p>
  
  <p>The problem is, that there are multiple product categories of the same name.</p>
  
  <p>Each product category has an associated 'System', so my question is, is there a way to modify:</p>
  
  <pre><code>echo $this-&gt;Form-&gt;input('product_cat_id');
  </code></pre>
  
  <p>which shows <code>Product Category</code> to show <code>System &gt;&gt; Product Category</code></p>
