kendo grid 过滤器

colums中：

filterable: { ui: chargeFilter }

Js中：

    var chs = ["是", "否"];
    function chargeFilter(element) {
        element.kendoDropDownList({
            dataSource: chs,
            optionLabel: "--请选择--"
        });
    };

 或者直接多选过滤

filterable: { multi: true }  //最简便

还有一种多选的过滤

// 下拉框过滤器或多选过滤器
// element 元素
// grid-表格
// field-要过滤的字段名称
// ds-下拉框或多选的数据源
// textField, valueField 下拉框或多选的显示设置
// optionText optionLabel
// type true-kendoMultiSelect; false-kendoDropDownList
