jQuery Grid Plugin - jqGrid

Dear All,

I trying to do

{ name: 'tblDepartment.Description', index: 'tblDepartment.Description', align: 'left', width: 90, editable: false, edittype: 'select', stype: 'select', surl: '@Url.Content("~/Home/DepartmentSelectDesc")', editoptions: { dataUrl: '@Url.Content("~/Home/DepartmentSelect")' }, sortable: true, search: true, searchoptions: { multiple: true, sopt: ['eq']} }, 

{ name:

'tblDepartment.Description', index: 'tblDepartment.Description', align: 'left', width: 90, editable: false, edittype: 'select', stype: 'select', surl: '@Url.Content("~/Home/DepartmentSelectDesc")', editoptions: { dataUrl: '@Url.Content("~/Home/DepartmentSelect")' }, sortable: true, search: true, searchoptions: { multiple: true, sopt: ['eq']} },

But the dropdown on the filter bar still not allow multiple select for filter. I not interested on multiSearch: true method. Looking for filterToolbar with multiple Select option.

Thank you.

Regards,

Micheale

Please advise.
