body: <p>I created a dynamic menu using jstree plugin, here my problem is to toggle the menu when we click on parent1 then the sub child will get opened and when i click on parent2 ie node two then i want to close the parent1.
  How to implement this.</p>
  
  <pre><code>node1
      sub1
      sub2parent
            sub1
            sub2
            sub3
      sub3
  
  node2
     sub1
     sub2
     sub3
  </code></pre>
  
  <p>here when i click on node one all sub are visible.
  when i click on node 2 then the node1 sub nodes and note2 sub nodes are visible </p>
  
  <p>what i need is when i click on node2 then node1 should get closed.</p>
