我在网上找到了一个jQuery Dropdown menu，但是问题是它是水平的，我的元素使用的是垂直菜单。这是代码:

HTML 代码:

    $(function() {

      $("ul.dropdown li").hover(function() {

        $(this).addClass("hover");
        $('ul:first', this).css('visibility', 'visible');

      }, function() {

        $(this).removeClass("hover");
        $('ul:first', this).css('visibility', 'hidden');

      });

      $("ul.dropdown li ul li:has(ul)").find("a:first").append(" » ");

    });
* {
  margin: 0;
  padding: 0;
}
body {
  font-family: Verdana, Geneva, sans-serif;
  font-size: 12px;
  background-color: #303030;
}
#page-wrap {
  width: 800px;
  margin: 25px auto;
}
a {
  text-decoration: none;
}
ul {
  list-style: none;
}
p {
  margin: 15px 0;
}
/*
     LEVEL ONE
     */

ul.dropdown {
  position: relative;
}
ul.dropdown li {
  font-weight: bold;
  float: left;
  zoom: 1;
  background: #000 url(../img/overlay2.png) repeat-x top left;
  -moz-border-radius: 5px;
  -webkit-border-radius: 5px;
  margin: 1px;
  text-shadow: 0 2px 1px rgba(0, 0, 0, 0.2);
}
ul.dropdown a:hover {
  color: #000;
}
ul.dropdown a:active {
  color: #ffa500;
}
ul.dropdown li a {
  display: block;
  padding: 4px 8px;
  color: #fff;
  text-shadow: 0 2px 1px rgba(0, 0, 0, 0.2);
}
ul.dropdown li:last-child a {
  border-right: none;
}
/* Doesn't work in IE */

ul.dropdown li.hover,
ul.dropdown li:hover {
  background: #0070C0;
  color: black;
  position: relative;
  color: #fff;
}
ul.dropdown li.hover a {
  color: #fff;
  font-weight: bold;
}
/*
     LEVEL TWO
     */

ul.dropdown ul {
  width: 220px;
  visibility: hidden;
  position: absolute;
  top: 100%;
  left: 0;
}
ul.dropdown ul li {
  font-weight: normal;
  background: #909090 url(../img/overlay2.png) repeat-x top left;
  color: #000;
  float: none;
}
/* IE 6 & 7 Needs Inline Block */

ul.dropdown ul li a {
  border-right: none;
  width: 100%;
  display: inline-block;
}
/*
     LEVEL THREE
     */

ul.dropdown ul ul {
  left: 100%;
  top: 0;
}
ul.dropdown li:hover > ul {
  visibility: visible;
}

CSS中使用的图像只是像管道一样的垂直线，overlay.png图像比overlay2.png长。

那么有没有可能把菜单做成垂直的呢？

最佳答案

你需要改变两件事

用波纹管替换ul.dropdown li

ul.dropdown li {
font-weight: bold;
width: 200px;
zoom: 1;
background: #000 url(../img/overlay2.png) repeat-x top left;
-moz-border-radius: 5px;
-webkit-border-radius: 5px;   
margin:1px;
text-shadow: 0 2px 1px rgba(0,0,0,0.2);
}

用波纹管替换 ul.dropdown ul

ul.dropdown ul {
    width: 220px;
    visibility: hidden;
    position: absolute;
    top: 100%;
    left:210px;
}

下面是演示

$(function(){

    $("ul.dropdown li").hover(function(){

        $(this).addClass("hover");
        $('ul:first',this).css('visibility', 'visible');

    }, function(){

        $(this).removeClass("hover");
        $('ul:first',this).css('visibility', 'hidden');

    });

    $("ul.dropdown li ul li:has(ul)").find("a:first").append(" &raquo; ");

});
 * {
    margin: 0;
    padding: 0;
}

body {
    font-family: Verdana,Geneva,sans-serif;
    font-size: 12px;
    background-color:#303030;
} 
#page-wrap {
    width: 800px;
    margin: 25px auto;
}

a {
    text-decoration: none;
}

ul {
    list-style: none;
}

p {
    margin: 15px 0;
}

/*

}

ul.dropdown a:hover {

ul.dropdown a:active {

ul.dropdown li a {
