title: checkbox for multiple level headers in Jquery Grid Multigrouping
body: <p>I am using jquery grid version 4.4.1 . I have used <strong>multiselect: true</strong> option to enable the checkboxes for all the rows. I am also using 2 level grouping i.e grouping by 2 fields. But i am not getting the checkboxes for those grouping headers. only my actual records are getting checkboxes. Please help me to know if there is any way we can use it.</p>
