制作“jsddm”菜单以列出子菜单

Question

你能帮我制作这个 jquery/css/menu 来显示第二级吗？

这是代码：

HTML

<ul id="jsddm">
    <li><a href="#">JavaScript</a>
        <ul>
            <li><a href="#">Drop Down Menu</a></li>
            <li><a href="#">jQuery Plugin</a></li>
            <li><a href="#">Ajax Navigation</a></li>
        </ul>
    </li>
    <li><a href="#">Effect</a>
        <ul>
            <li><a href="#">Slide Effect</a></li>
            <li><a href="#">Fade Effect</a></li>
            <li><a href="#">Opacity Mode</a></li>
            <li><a href="#">Drop Shadow</a></li>
            <li><a href="#">Semitransparent</a></li>
        </ul>
    </li>
    <li><a href="#">Navigation</a></li>
    <li><a href="#">HTML/CSS</a></li>
    <li><a href="#">Help</a></li>
</ul>

CSS

#jsddm
{   margin: 0;
    padding: 0}

    #jsddm li
    {   float: left;
        list-style: none;
        font: 12px Tahoma, Arial}

    #jsddm li a
    {   display: block;
        background: #20548E;
        padding: 5px 12px;
        text-decoration: none;
        border-right: 1px solid white;
        width: 70px;
        color: #EAFFED;
        white-space: nowrap}

    #jsddm li a:hover
    {   background: #1A4473}

        #jsddm li ul
        {   margin: 0;
            padding: 0;
            position: absolute;
            visibility: hidden;
            border-top: 1px solid white}

        #jsddm li ul li
        {   float: none;
            display: inline}

        #jsddm li ul li a
        {   width: auto;
            background: #9F1B1B}

        #jsddm li ul li a:hover
        {   background: #7F1616}

JQUERY

    var timeout    = 500;
var closetimer = 0;
var ddmenuitem = 0;

function jsddm_open()
{  jsddm_canceltimer();
   jsddm_close();
   ddmenuitem = $(this).find('ul').css('visibility', 'visible');}

function jsddm_close()
{  if(ddmenuitem) ddmenuitem.css('visibility', 'hidden');}

function jsddm_timer()
{  closetimer = window.setTimeout(jsddm_close, timeout);}

function jsddm_canceltimer()
{  if(closetimer)
   {  window.clearTimeout(closetimer);
      closetimer = null;}}

$(document).ready(function()
{  $('#jsddm > li').bind('mouseover', jsddm_open)
   $('#jsddm > li').bind('mouseout',  jsddm_timer)});

document.onclick = jsddm_close;

我怎样才能插入一个多级菜单并使其工作？，我已经在这里卡了几天了。

谢谢！

完全不使用 jQuery，只使用 CSS 作为菜单怎么样？
