title: Ext JS components within an expanded row
body: <p><em>Simple question here</em>: I have a working grid with expanding rows within my Ext JS application. <strong>Boom.</strong></p>
  
  <p>Currently I have <code>html</code> elements inside of my expanded row (it's just one big <code>div</code>), but that seems to be all the expanded row is capable of displaying.</p>
  
  <p>Is there anyway to render Ext components <em>inside</em> of my expanded rows?</p>
  
  <p>Cheers mates, upvotes await!</p>
