我有一个下拉菜单，当它被选中时，如下图所示：

在此处输入图像描述

应该有一个比“快速观看”更长的列表，但它似乎被切断了，这是为什么呢？

HTML：

<div id="top_bar">
<div id="top_inner">
<div id="logo"> <a href="http://www.edosbornephotography.com"><img src="images/logo.gif" alt="Ed Osborne" width="225" height="115" class="logo"></a></div>
<div class="nav">
<ul class = "menu" >
            <li> <a href = "#" > Home </a> </li>
            <li><a href = "#" > Tutorials </a>
        <ul class = "submenu" >
            <li> <a href = "#" > CSS </a> </li>
            <li> <a href = "#"> Javascript </a> </li>
            <li> <a href = "#" > jQuery </a> </li>
            <li> <a href = "#"> HTML </a> </li>
            <li> <a href = "#" > PHP </a> </li>
        </ul>
        </li>

        </ul>
        </li>

        <li> <a href = "#" > About Us </a> </li>
        <li> <a href = "#" > Privacy </a> </li>

        <li> <a href = "#" > Contact </a> </li>
        </ul>
    </div>
</div>

<div></div>
</body>
</html>

CSS：

#top_bar {

ul.menu {

}

ul.menu li span.subhover {background-position: center bottom; cursor: pointer;} 

ul.menu li ul.submenu {

border: 1px solid #111;
}

ul.menu li ul.submenu li{
margin: 0; padding: 0;
border-top: 1px solid #252525; 
border-bottom: 1px solid #444; 
clear: both;
width: 170px;
}

ul.menu li ul.submenu li a {
float: left;
width: 145px;
background: #333 url(../images/dropdown_linkbg.gif) no-repeat 10px center;
padding-left: 20px;
}

ul.menu li ul.submenu li a:hover { 
background: #222 url(../images/dropdown_linkbg.gif) no-repeat 10px center; 
}

任何人都可以解决这个问题吗？

谢谢

添加

ul.menu li:hover ul { display:block; }

并从中删除

#top_bar { overflow: hidden; }
