如何定义默认情况下应该在“menu1”下显示“submenu11”的内容?
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
</head>
<body>
<ul id="css3menu1" class="menu">
<li class="topfirst"><a class="pressed" href="#menu1" style="height:40px;line-height:40px;"><span><img src="menu_files/css3menu1/db.png"/>MENU1</span></a>
<ul>
<li><a href="#submenu11">SUBMENU11</a></li>
<li><a href="#submenu12">SUBMENU12</a></li>
<li><a href="#submenu13">SUBMENU13</a></li>
<li><a href="#submenu14">SUBMENU14</a></li>
</ul></li>
<li class="menu"><a href="#menu2" style="height:40px;line-height:40px;"><img src="menu_files/css3menu1/schedule.png"/>MENU2</a></li>
<li class="menu"><a href="#menu3" style="height:40px;line-height:40px;"><img src="menu_files/css3menu1/analysis.png"/>MENU3</a></li>
<li class="toplast"><a href="#menu4" style="height:40px;line-height:40px;"><img src="menu_files/css3menu1/gps.png"/>MENU4</a></li>
</ul>
