title: Typo3 Dropdown with three layers
body: <p>I have to implement a dropdown menu which looks like this:</p>
  
  <pre><code>MenuItem
     Section1
        Article1
        Article2
     Section2
        Article3
        Article4
        etc.
  </code></pre>
  
  <p>There are three layers: </p>
  
  <pre><code>  Layer1: MenuItem
    Layer2: Section1, Section2
    Layer3: ArticleX
  </code></pre>
  
  <p>If I hover over 'MenuItem' it should expand and show the other two layers. But the third layer should be a little intendet.</p>
  
  <p>I'm using Typo3 6.0.1. I hope my question is clear to you.</p>
  
  <p>Regards</p>
