title: jqgrid multiselect enable/ disable checkbox
body: <p>I'm trying to enable/disable the multiselect checkboxes (not hide the entire column) when a button is pressed(enters in edition mode).</p>
  
  <p>my jqGrid version is 4.6.0.</p>
  
  <p><a href="http://www.ok-soft-gmbh.com/jqGrid/HideMultiselectColumn.htm" rel="nofollow">this</a> is not what i'm looking for.</p>
  
  <p>Is there an option for this or do I have to disable the row by row?</p>
  
  <p>I've looked in the documentation at <a href="http://www.trirand.com/jqgridwiki/doku.php?id=wiki:options" rel="nofollow">http://www.trirand.com/jqgridwiki/doku.php?id=wiki:options</a></p>
  
  <p>and I can't find something like what I wnat to do</p>
  
  <p>thank you in advance</p>
