            initComplete: function () {
                /*this.api().columns().every(function () {*/
                this.api().columns([4, 8, 11, 12, 13]).every(function () {
                    var column = this;
                    var select = $('<select class="myselect"><option value=""></option></select>')
                        .appendTo($(column.footer()).empty())
                        .on('change', function () {
                            var val = $.fn.dataTable.util.escapeRegex(
                                $(this).val()
                            );

                                .draw();
                        });


                    column.data().unique().sort().each(function (d, j) {
                        select.append('<option value="' + d + '">' + d + '</option>')
                    });



                });
            },
            "order": [[12], [1, "desc"]],
            /*"order": [[13, 11, 9, "desc"]],*/
            /*"ordering": false,*/
            'aoColumnDefs': [{
                'bSortable': false,
                'aTargets': [-1, -5, -6, -7, -8, -11, -12] /* 1st one, start by the right */
            }],
            "stateSave": true, 
            "stateDuration": 60 * 10, 
            "pageLength": 10
        });
    });

</script>

Thanks...

Hi @tonj83 ,

Yep, stateSave , by default, will only save things it knows about - i.e. column ordering, table filtering, etc. Because that column filter is something you added to the the table, you need to instruct stateSave how to save those values, and how to retrieve them.

This example here from this thread should help - it's saving the selected rows, you would do something similar to save the searches,

Cheers,

Colin
