title: Create scrollbars one an ext js dataview
body: <p>On the project I am working on I have a dataview inside a panel which is constrained in size. I am having trouble figuring out how I can put scrollbars on the view to make sure that all the items in the dataview can all be displayed if they overflow the size of the dataview/panel. My code is very similar to that on <a href="http://try.sencha.com/extjs/4.0.7/examples/view/data-view/viewer.html" rel="nofollow">http://try.sencha.com/extjs/4.0.7/examples/view/data-view/viewer.html</a>.</p>
  
  <p>If you edit this code and change the width of the dataview to something smaller e.g. 310 you will see that the images overflow the panel and are hidden. How can I put a scrollbar on this so that I can scroll to the hidden items? I have tried 'autoscroll: true' to no effect.</p>
