有没有人能为我提供一个基本的3级崩溃菜单的引导导航栏？
我不打算打开第三级.有人可以调整我的代码来添加第三级吗？
我不打算打开第三级.有人可以调整我的代码来添加第三级吗？
这是我有两个级别的菜单：
<div class="navbar navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
<a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</a>
<div class="nav-collapse">
<ul class="nav">
<a class="brand" href="#">Present Ideas</a>
<li class="active"><a href="#">Home</a></li>
<li><a href="#">Blog</a></li>
<li><a href="#">About</a></li>
<li><a href="#">Help</a></li>
<li class="dropdown" id="accountmenu">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">Account Settings<b class="caret"></b></a>
<ul class="dropdown-menu">
<li><a href="#">Login</a></li>
<li><a href="#">Register</a></li>
<li class="divider"></li>
<li><a href="#">logout</a></li>
</ul>
</li>
</ul>
<ul class="nav pull-right">
</ul>
</div>
<!--/.nav-collapse -->
</div>
</div>
</div>
我以为像：
<div class="navbar navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
<a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</a>
<div class="nav-collapse">
<ul class="nav">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">Blog</a></li>
<li><a href="#">About</a></li>
<li><a href="#">Help</a></li>
<li class="dropdown" id="accountmenu">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">Account Settings<b class="caret"></b></a>
<ul class="dropdown-menu">
<li><a href="#">Login</a></li>
<li class="item-148 dropdown parent">
<a href="/about/learn-more">Learn more <b class="caret-right"></b></a>
<ul class="dropdown-menu">
<li class="item-149"><a href="/about/learn-more/the-software">The Software</a></li>
<li class="item-150"><a href="/about/learn-more/the-project">The Project</a></li>
<li class="item-151"><a href="/about/learn-more/the-leadership">The Leadership</a></li>
<li class="item-152"><a href="/about/learn-more/open-source-matters">Open Source Matters</a></li>
</ul>
</li>
<li class="divider"></li>
<li><a href="#">logout</a></li>
</ul>
</li>
</ul>
<ul class="nav pull-right">
</ul>
</div>
<!--/.nav-collapse -->
</div>
</div>
</div>
但这不行
解决方法
Bootstrap 2.3.x及更高版本支持下拉菜单.
<ul class="dropdown-menu">
<li><a href="#">Login</a></li>
<li class="dropdown-submenu">
<a tabindex="-1" href="#">More options</a>
<ul class="dropdown-menu">
<li><a tabindex="-1" href="#">Second level</a></li>
<li><a href="#">Second level</a></li>
<li><a href="#">Second level</a></li>
</ul>
</li>
<li><a href="#">logout</a></li>
</ul>
