你必须点击标题为它显示出来，否则，菜单是隐藏的。下面

CSS：

#top_nav{ width: 810px; float: left; background: #DADADA; margin: 0; position: relative; z-index: 100; padding: 0;} 
#top_nav ul {margin: 0 0 0 10px; padding: 0; list-style: none; float: left; width: 800px; height: 40px; } 
#top_nav li {float: left; margin: 0; padding: 0; width: auto; font-weight: normal; cursor: pointer; white-space: nowrap; font-size: 100%; color: #000; line-height: 150%;} 
#top_nav li a{text-decoration: none; color: #000; width: auto; display: block; padding: 8px 18px 7px 18px; line-height: 25px; text-align: center; font-weight: normal; } 



#top_nav li ul {position: absolute; left: -999em; height: auto; width: 234px; w\idth: 224px; font-weight: normal; padding: 0px 0 0 0; margin: 0 0 0 0; border-bottom: 1px solid #aaa; } 
#top_nav li li {padding: 0; background-color: #DADADA; font-size: 90%; line-height: 120%;} 

#top_nav li li a{line-height: auto; text-align: left; width: 212px; w\idth: 202px; padding: 3px 10px; border-top: 1px solid #aaa; border-left: 1px solid #aaa; border-right: 1px solid #aaa; } 
#top_nav li li a:hover{ background-color: #92D400; color: #fff;} 

#top_nav li:hover ul ul, #top_nav li:hover ul ul ul, #top_nav li.sfhover ul ul, #top_nav li.sfhover ul ul ul {left: -999em;} 
#top_nav li:hover ul, #top_nav li li:hover ul, #top_nav li li li:hover ul, #top_nav li.sfhover ul, #top_nav li li.sfhover ul, #top_nav li li li.sfhover ul { left: auto;} 
#top_nav li:hover, #top_nav li.sfhover, #top_nav a.active{ background-color: #92D400; } 

#sub_nav{ background: #002F5F; float: left; width: 810px; margin: 0; } 
#sub_nav ul{ float: left; width: 790px; margin: 0 0 0 10px; padding: 0; list-style: none; } 
#sub_nav li{ float: left; margin: 0; padding: 0; font-size: 90%; font-weight: bold; text-align: center; } 
#sub_nav li a{ color: #fff; display: block; height: 105px; padding: 8px 30px 0 30px; text-decoration: none; } 
#sub_nav li a:hover, 
#sub_nav li a.active{ background-color: #DADADA; color: #002F5F; } 

#section_nav{ float: left; margin: 1px 0 0px 0; width: 810px; background: #002F5F; } 
#section_nav ul{ float: left; width: 808px; margin: 0; padding: 0; list-style: none; } 
#section_nav li{ float: left; margin: 0; padding: 0; font-size: 70%; font-weight: bold; } 
#section_nav li a{ color: #fff; display: block; padding: 8px 10px; border-right: 1px solid #fff; border-bottom: 1px solid #fff; text-decoration: none; } 
#section_nav li a:hover, 
#section_nav li a.active{ background: #92D400;} 
#section_nav img{ float: left; margin: 2px 0 0 2px;}

的下拉菜单不会自动在IE8中工作，你还必须点击标题为它显示出来。下面列出

HTML：

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

<script type="text/javascript" src="js/jquery.min.1.7.1.js"></script> 

<link rel="stylesheet" href="js/nivo-slider/nivo-slider.css" type="text/css" media="screen" /> 
<script src="js/nivo-slider/jquery.nivo.slider.pack.js" type="text/javascript"></script> 

<script type="text/javascript"> 
jQuery(window).load(function() { 
var total = jQuery('#slider img').length; 
var rand = Math.floor(Math.random()*total); 
jQuery('#slider').nivoSlider({ 
    animSpeed: 1000, // Slide transition speed 
    pauseTime: 4000, // How long each slide will show 
    directionNav: false, 
    effect: 'boxRainGrow' 
}); 

}); 
</script> 

<script type="text/javascript"> 
$(function(){ 
    $('a[href*=#]').click(function() { 
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') 
     && location.hostname == this.hostname) { 
      var $target = $(this.hash); 
      $target = $target.length && $target || $('[name=' + this.hash.slice(1) +']'); 
      if ($target.length) { 
       var targetOffset = $target.offset().top; 
       $('html,body').animate({scrollTop: targetOffset}, 500); 
       return false; 
      } 
     } 
    }); 
}); 
</script>

你有什么试过吗？你从你的菜单中除了什么行为？你能告诉我们HTML代码吗？ – Bigood 2013-02-12 14:05:54

你能给我们一个链接到你的代码？或者在http://jsfiddle.net上发布你的代码 – Mike 2013-02-12 14:28:01

好的，将编辑我的quey添加代码 - 谢谢 – user2054233 2013-02-12 15:23:00

“z索引：X;”解决了我的CSS下拉菜单和jQuery滑块（幻灯片/旋转木马）之间的冲突。这是很容易解决许多人似乎有问题。

尝试把该下的下拉UL的CSS样式。

例

.navbar ul .subnav { 
display: none; 
z-index: 3; 
}

你可以玩的数量（X）。
