Estoy usando la última versión de metronic. He habilitado la propiedad de searching:true pero aún no funciona

 dt = $(tablename).DataTable({ searchDelay: 500, processing: true, serverSide: true, responsive:true, order: [], searching:true, stateSave: true, aoColumnDefs: [ { bSortable: false, aTargets: ["nosort"], }, ], select: { style: 'os', selector: 'td:first-child', className: 'row-selected' }, ajax: { url: url, data: filters, }, // Add data-filter attribute // createdRow: function (row, data, dataIndex) { // $(row).find('td:eq(4)').attr('data-filter', data.CreditCardType); // } }); var table = dt.$; // Re-init functions on every table re-draw -- more info: https://datatables.net/reference/event/draw dt.on('draw', function () { // initToggleToolbar(); // toggleToolbars(); //handleDeleteRows(); KTMenu.createInstances(); });
