title: jqGrid: Editable column that always shows a select
body: <p>Is there a way in jqgrid to have an editable column that uses a select like in this colModel example:</p>
  
  <pre><code>{ 
  name: 'Options', 
  index: 'Options', 
  width: 150, 
  align: 'left', 
  resizable: false,
  editable: true, 
  edittype: 'select', 
  editoptions: { 
      value: function() { return buildSelect(); } 
  },
  formatter: 'select'
  }
  </code></pre>
  
  <p>but always shows the select?</p>
  
  <p>I've got this working before with checkboxes, but there doesn't seem to be a way of doing it with selects. Ideally I'd like this to work in celledit mode. Any ideas?</p>
