title: Finding a subtree in a CakePHP Tree
body: <p>In CakePHP, how do you select just a subtree in a model which <code>actsAs</code> tree?</p>
  
  <p>I tried this, to find the tree headed by the item with <code>label = "My Label"</code></p>
  
  <pre><code>$this-&gt;find("threaded", array(
      "conditions" =&gt; array(
          "label" =&gt; "My Label"
      )
  ));
  </code></pre>
  
  <p>...however looking at the logs, it runs this SQL:</p>
  
  <pre><code>SELECT Menu.id, Menu.parent_id, Menu.lft, Menu.rght, Menu.label, Menu.link
  FROM menus Menu
  WHERE label = 'My Label'
  </code></pre>
  
  <p>Which obviously only selects the one node, and not all its children.</p>
