title: Slide down menu with check boxes in android
body: <p>I've been looking around and searching all over the internet on how to do this. I am really baffled here because I don't think this is a built-in widget for the android API. What I am trying to build is a "list" of items that when an item is clicked, it shows a series of check boxes below it. An example on my EVO is the "News" application when you go to "Add Feeds". I'll try and draw it out here:</p>
  
  <pre><code>BEFORE NEWS IS PRESSED:
  
  News       &gt;
  
  AFTER NEWS IS PRESSED:
  
  News       (arrow points down)
     CNN.com      (checkbox)
     Yahoo.com    (checkbox)
  </code></pre>
  
  <p>I'm sure this has to be custom made but I don't know where to start. Any help is appreciated.</p>
