title: Hide expand/collapse symbol or deactivate spec. rows in jqGrid subgrid
body: <p>I have a grid with a subgrid: Only the <strong>first</strong> row of the Main grid need to have a subgrid.</p>
  
  <p>The solutions I found by Google and <a href="http://www.trirand.com/jqgridwiki/doku.php?id=wiki%3asubgrid&amp;s%5b%5d=hidecol" rel="nofollow">http://www.trirand.com/....i:subgrid&amp;s[]=hidecol</a> 
  doesn't work.</p>
  
  <p>Is there a quick and dirty (hard coded) solution?</p>
