title: DynaTree: How do you expand all children ( downstream node levels) from a active node?
body: <p>I've got a 4 level tree and would like to expand all of its children (and children's children) when a level 2 node is activated.  I can determine the current activate node level with:</p>
  
  <pre><code>if(node.getLevel() == 2)...
  </code></pre>
  
  <p>I thought something like:</p>
  
  <pre><code>if(node.getLevel() == 2) node.expand(true)
  </code></pre>
  
  <p>But that doesn't work.</p>
