title: Dc-sunburst, dc-Menuslect, dc-Non interactive graph
body: <p>I'm new on dc.js and I have some questions about flexibility of dc. </p>
  
  <p>First, I have looked for answers but haven't yet found any of them.</p>
  
  <p>1) I'm using dc.sunburst chart. I was wondering if it was possible to create Zoomable sunburst as it is actually the case with d3.js. If yes, can you provide a piece of code please..?</p>
  
  <p>2) I'm using crossfilter for interacting several graphs together. However I would like that one of them would not be possible to filter with. I mean that it updates with his dimension/group when filtering on other chart but that filtering other chart clicking on it would be impossible. Any ideas ? </p>
  
  <p>Like: <code>dc.rowChart().on("click", Do not filter)</code></p>
  
  <p>3) I want to create a <code>dropdown</code> (using <code>dc.menuSelect</code> and <code>crossfilter</code>) on a two-dimension. When I create this chart the <code>dropdown</code> is like:</p>
  
  <ul>
  <li>Bâle, A1</li>
  <li>Bâle, A2</li>
  <li>...</li>
  <li>Bâle, N2</li>
  </ul>
  
  <p>And I would like something more like:</p>
  
  <ul>
  <li>Bâle
  
  <ul>
  <li>A1</li>
  <li>A2</li>
  <li>...</li>
  <li>N2</li>
  </ul></li>
  <li>Zürich
  
  <ul>
  <li>A1</li>
  <li>...</li>
  <li>N2</li>
  </ul></li>
  </ul>
  
  <p>Thanks for your answer !!</p>
