Kendo UI目前最新提供Kendo UI for jQuery、Kendo UI for Angular、Kendo UI Support for React和Kendo UI Support for Vue四个控件。Kendo UI for jQuery是创建现代Web应用程序的最完整UI库。
默认情况下，Kendo UI Grid过滤功能处于禁用状态。要控制Grid中的过滤，请使用filterable属性。
Grid使您可以实现以下过滤器选项：
要启用网格标题中的过滤器行，请将模式设置为row。结果基于基础列数据的数据类型，网格将在列标题中呈现字符串值、数字输入或日期选择器的文本框进行过滤。您还可以指定默认的过滤器运算符，当用户在过滤器文本框中输入值并从键盘按Enter或Tab时将应用该默认过滤器。 要处理这种情况，请将相应列的cell设置为operator。

要在过滤器菜单中呈现复选框列表，请为所需的Grid列设置multi=true，还可以将复选框过滤器与itemTemplate定义结合使用，并自定义将显示的复选框项目。

您可以为网格过滤器的菜单配置应用通用设置，并在每列中自定义其UI。有关实现自定义菜单筛选的可运行示例演示了如何：
<!DOCTYPE html>

<link rel="stylesheet" href="styles/kendo.common.min.css" />
<link rel="stylesheet" href="styles/kendo.default.min.css" />
<link rel="stylesheet" href="styles/kendo.default.mobile.min.css" />
<script src="js/jquery.min.js"></script>
<script src="js/kendo.all.min.js"></script>
</head>
<body>
<script src="../content/shared/js/people.js"></script>
<div id="example">
<div id="grid"></div>
<script>
$(document).ready(function() {
$("#grid").kendoGrid({
dataSource: {

BirthDate: { type: "date" }
}
}
},
pageSize: 15
},

filterable: {
