Input，用于表单，可以分成“输入型”和“选择型”两种。输入型包括单行文本（文本、数值、电话、密码等）、多行文本；选择型包括下拉选择、单选、多选、开关、日期时间等。在 WeUI 中，表单通常与 Cell 组件配合使用。

    示例代码如下：

    1. <div class="weui-cells__title">单选列表项</div>
    2. <div class="weui-cells weui-cells_radio">
    3.     <label class="weui-cell weui-check__label" for="x11">
    4.         <div class="weui-cell__bd">
    5.             <p>cell standard</p>
    6.         </div>
    7.         <div class="weui-cell__ft">
    8.             <input type="radio" class="weui-check" name="radio1" id="x11">
    9.             <span class="weui-icon-checked"></span>
    10.         </div>
    11.     </label>
    12.     <label class="weui-cell weui-check__label" for="x12">
    13.  
    14.         <div class="weui-cell__bd">
