title: jstree - expand branch to a specific grand-child
body: <p>I have a (js)Tree which is deep 3 levels or more. Although I have the entire tree data pre-loaded, the tree is collapsed, except for the root node. On a specific js event, I want to expand a particular node (I have its ID/selector). How would I go about it?</p>
  
  <p>At the moment I can only:</p>
  
  <pre><code>placeholder.find(".jstree").jstree("open_all");
  placeholder.find(".jstree").jstree("select_node", "[data-xxx = '" + yyy + "']");
  </code></pre>
  
  <p>which expands EVERYTHING and selects the given node. I want to achieve the same thing, but expanding only the branch(es) which lead to my node.</p>
  
  <p>To put it in pictures, what my code does is:

  <p>I am using the latest version of jsTree.</p>
