如何使用：

第1步、引用CSS和JS：

<link type="text/css" href="~/Scripts/DivSelect/divSelect.css" rel="stylesheet" />
<script type="text/javascript" src="~/Scripts/jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="~/Scripts/DivSelect/divSelect.js"></script>

View Code

第2步、给select控件加上class="div-select-target" width="200"，其中class="div-select-target"是必须的，width="200"是可选的。完整HTML代码如下：

<link type="text/css" href="~/Scripts/DivSelect/divSelect.css" rel="stylesheet" />
<script type="text/javascript" src="~/Scripts/jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="~/Scripts/DivSelect/divSelect.js"></script>

<div style="border: solid 1px #f99; margin: 50px; padding: 50px;">
    <select name="sel" class="div-select-target" width="200" >
        <option value="1">中国</option>
        <option value="2">美国</option>
        <option value="3">法国</option>
        <option value="4">英国</option>
        <option value="5">俄罗斯</option>

        <option value="20">新西兰</option>
        <option value="21">挪威</option>
        <option value="22">巴勒斯坦</option>
        <option value="23">以色列</option>
        <option value="24">新加坡</option>
        <option value="25">马来西亚</option>

        <option value="37">国家37</option>
        <option value="38">国家38</option>
    </select>
</div>
<div style="border: solid 1px #f99; margin: 50px; padding: 50px; margin-top: 700px; margin-bottom: 700px;">
    <select name="sel" class="div-select-target" width="200" >
