      $(document).ready(function() {
          placeholder: "Select product",
          dataTextField: "ProductName",
          dataValueField: "ProductID",
          filter: "contains",
          autoBind: false,
          minLength: 3,
          dataSource: {
            type: "odata",
            serverFiltering: true,
            transport: {
              read: {
                url: "https://demos.telerik.com/kendo-ui/service/Northwind.svc/Products",
          open: function() {
            var filters = this.dataSource.filter();

            if (filters) {
              //clear applied filters

    <style scoped>
      .demo-section {
        width: 400px;
