Html的代码如下：

<!DOCTYPE html>
<html>

<head>

  <meta charset="UTF-8">

  <title>垂直下拉菜单</title>

  <meta name="viewport" content="width=device-width, initial-scale=1">

    <link rel="stylesheet" href="css/style.css" media="screen" type="text/css" />

</head>

<body>Accordion
<div style="text-align:center;clear:both">
</div>
    <!-- Contenedor -->
    <div id="page-sidebar-menu" class="page-sidebar-menu">
        <p class="tab-link"><a class="left-a" href="javascript:void(0)" title="系统日志">系统日志1</a></p>
            <ul class="submenu">
                <li><a href="#">Photoshop1</a></li>
                <li><a href="#">HTML1</a></li>
                <li><a href="#">CSS1</a></li>
                <li><a href="#">Maquetacion web1</a></li>
            </ul>
        <p class="tab-link"><a class="left-a" href="javascript:void(0)" title="系统日志">系统日志2</a></p>
        <p class="tab-link"><a class="left-a" href="javascript:void(0)" title="实盘监控">实盘监控3</a></p>
            <ul class="submenu">
                <li><a href="#">Photoshop3</a></li>
                <li><a href="#">HTML3</a></li>

                <li><a href="#">Maquetacion web3</a></li>
            </ul>
        <p class="tab-link"><a class="left-a" href="javascript:void(0)" title="实盘监控">实盘监控4</a></p>
            <ul class="submenu">
                <li><a href="#">Photoshop4</a></li>

            </ul>
        <p class="tab-link"><a class="left-a" href="javascript:void(0)" title="实盘监控">实盘监控5</a></p>
            <ul class="submenu">

                <li><a href="#">HTML5</a></li>
                <li><a href="#">CSS5</a></li>
                <li><a href="#">Maquetacion web5</a></li>
            </ul>
    </div>

  <script src=‘js/jquery-1.10.2.js‘></script>

  <script src="js/index.js"></script>

</body>

</html>
$(function() {
    var Accordion = function(el, multiple) {
        this.el = el || {};
        this.multiple = multiple || false;

        var links = this.el.find(‘.tab-link‘);

        links.on(‘click‘, {el: this.el, multiple: this.multiple}, this.dropdown)
    }

    Accordion.prototype.dropdown = function(e) {
        var $el = e.data.el;
            $this = $(this),
            $next = $this.next();
            if($next.find(‘li‘).length ==0){
                return false;    
            }
            $next.slideToggle();

            $next.find(‘li‘).click(function() {
                $(this).addClass(‘activeLi‘).siblings().removeClass(‘activeLi‘);
            });

            $this.toggleClass(‘open‘);
            if (!e.data.multiple) {
                var oth =$el.find(‘.submenu‘).not($next);
                    oth.slideUp().parent().removeClass(‘open‘);
                    oth.find(‘li‘).removeClass(‘activeLi‘);
            };    
    }    

    var accordion = new Accordion($(‘#page-sidebar-menu‘), false);
});

CSS代码：

　

 div,p,ul,li{
    margin: 0;
    padding: 0;
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
}
    ul li{
        list-style-type: none;
    }
 .page-sidebar-menu .left-a {
        display: block;
        font-size:12px;
        color:#03478b;
        text-decoration: none;
        -webkit-transition: all 0.4s ease;
        -o-transition: all 0.4s ease;
        transition: all 0.4s ease;
    }
    .page-sidebar-menu li.active {
        background: #bbbbbb;
    }
    .tab-link{
        padding:5px;
        margin:2px 0;
        background-color:#E4EFFB;
    }
    p.active {
        background: #5A86A8;
    }
    .page-sidebar-menu p.active a {
        color:#fff;
    }
    .submenu {
        display: none;
        background: #444359;
        font-size: 14px;
    }

    .submenu li {
        border-bottom: 1px solid #4b4a5e;
    }

    .submenu a {
        display: block;
        text-decoration: none;
        color: #d9d9d9;
        font-size: 12px;
        padding: 5px;
        -webkit-transition: all 0.25s ease;
        -o-transition: all 0.25s ease;
        transition: all 0.25s ease;
    }

    .submenu a:hover {
        background: #E4EFFB;
        color: #000;
    }
