我正在使用bootstrap 3构建一个网页,我遇到了多个固定导航栏的问题。我已经一个接一个地安排固定的导航栏并且我面临的问题是,第一个固定导航栏中的下拉列表不完全可见,因为第二个固定导航栏正在隐藏它。
我尝试将下拉列表的z-index设置为更高的值但是,它不起作用。

代码:
<nav class="navbar navbar-default navbar-fixed-top">
<div class="container-fluid">
<img src="https://cdn4.iconfinder.com/data/icons/SUPERVISTA/animals/png/48/swallow_bird.png"></img>
<ul class="nav navbar-nav pull-right">
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Action Links <span class="caret"></span></a>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li role="separator" class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</li>
</ul>
</div>
</nav>
<nav class="navbar navbar-inverse navbar-fixed-top nav2">
<div class="container-fluid">
<p class="navbar-text">Instruction will appear here...</p>
</div>
</nav>
期望:
下拉项目应显示在第二个固定导航栏上方。任何建议都表示赞赏。

您可以更改DOM中元素的顺序吗?
如果是这样,只需将.navbar-fixed-top2
放在.navbar-fixed-top
之前。

尝试以下小提琴:
http://docs.oracle.com/javase/7/docs/api/java/util/List.html
我添加了一些CSS:
#actionlinks{
position:relative;
z-index:50;
}
.nav2{
position:relative;
z-index:30;
}
和actionLinks的ID

您可以将两个导航栏括起来以便修复它们并且您有一些应该调整的HTML请参阅Docs。
请参阅示例代码段。
.navbar .navbar-brand {
padding: 1px 5px;
margin: 0;
height: 30px;
}
.navbar.navbar-top {
margin-bottom: 0;
}

我将底部导航栏的z-index缩小为负值并且有效。
<nav class="navbar navbar-inverse navbar-fixed-top nav2" style="z-index:-100;">
<div class="container-fluid">
<p class="navbar-text">Instruction will appear here...</p>
</div>
</nav>
