<select name="filter" id="filter"  class="select2"  multiple="multiple" >


        placeholder: ' Users',
        ajax: {
            url: [AJAX_URL],
            dataType: 'json',
            type: 'GET',
            data: function (term) {
                return {
                    term: term
            processResults: function (data) {
                return {
                    results: $.map(data, function (item) {
                        return {
                            text: item.username,
                            id: item.username
