1.下载插件文件

2.显示层引入文件

<script type="text/javascript" src="__PUBLIC__/javascripts/admin/chosen.jquery.js"></script><link rel="stylesheet" href="__PUBLIC__/stylesheets/admin/chosen.css"/>

3.编写需要插件的输入框

<select name="id" data-placeholder="Choose a Country" class="chosen-select" tabindex="2" style="width: 180px;"> <option value="">---请选择账号-</option> <volist name="accounts" id="account"> <option value="{$account.id}">{$account.account}</option> </volist> </select>

<script>
    $(function () {
        $('.chosen-select').chosen();
        $('.chosen-select-deselect').chosen({allow_single_deselect: true});
    });
</script>

就是这么简单.插件效果图如下:
