title: Create Header for Kendo UI Menu for sub items group
body: <p>I'm trying to add a Header to a kendo Menu items group when the item is selected its subitems group should display a header with the parent name. I'm creating the menu thru a datasource dynamically. How can I add a <code>&lt;div&gt;</code> or <code>&lt;h2&gt;</code> tag to achieve this?</p>
  
  <p>Example:</p>
  
  <pre><code>Menu 1 ^
    Item 1   &gt;   Item 1
    Item 2       Sub Item 1
    Item 3       Sub Item 2
                 Sub Item 3
  </code></pre>
