title: How can I add a checkbox into a jQgrid header
body: <p>Each jQgrid row has multiple checkboxes, so I cannot use (just) the multiselect.</p>
  
  <p>This is how the column is setup...</p>
  
  <blockquote>
    <p>{ name: 'ColName', label: '', width: 50,
    editable: true, sortable: false, edittype: "checkbox", formatter:
    'checkbox', formatoptions: { disabled:false}, index:"my_checkbox",
    editoptions: {value:"Yes":"No"} }</p>
  </blockquote>
  
  <p>When I click the checkbox in the header, the header is redrawn without the check.  I can capture the event, but cannot display the check to the user.</p>
  
  <p>So my question would be, how can I get a checkbox to operate normally inside a header label OR how can I implement multiple multiselects.</p>
