title: Snapjs Drawer issue and scrolling content
body: <p>I am using snap JS such that I have a drawer on the left and content to the right. However when the drawer is opened, I can still scroll content on the left. </p>
  
  <p>What would be the right way so that I can disable the div on the left. In jQuery:</p>
  
  <pre><code> if (state == 'right')
                    "disable the left side so you can't scroll' (  $('.idofelement').disable();)  ; 
  </code></pre>
  
  <p>Is there something that I am overlooking in snap where within the controller the left can be disabled, without DOM manipulation.</p>
