mui-checkbox
复选框
checkbox常用于多选的情况，比如批量删除、添加群聊等；
DOM结构
<div class="mui-input-row mui-checkbox">
<label>checkbox示例</label>
<input name="checkbox1" value="Item 1" type="checkbox" checked>
</div>
默认checkbox在右侧显示，若希望在左侧显示，只需增加.mui-left类即可，如下：
<div class="mui-input-row mui-checkbox mui-left">
<label>checkbox左侧显示示例</label>
<input name="checkbox1" value="Item 1" type="checkbox">
</div>
若要禁用checkbox，只需在checkbox上增加disabled属性即可；
