我有以下代码来创建下拉菜单。但是,在任何具有嵌入PDF的页面上,PDF下方会显示下拉列表。它似乎只发生在IE中。有什么问题吗?
In [45]: res['new'] = 0.3
In [46]: res
Out[46]:
key val new
0 1.H1' 5.82020 0.3
2 2.H1' 5.90291 0.3
3 4.H1' 5.74125 0.3
4 3.H1' 5.54935 0.3
8 6.H1' 5.54297 0.3
10 2.H8 7.61004 0.3
11 1.H8 8.13712 0.3
13 3.H6 7.53261 0.3
14 4.H8 7.49932 0.3
18 5.H6 7.72158 0.3

这里是嵌入式PDF的代码:
<nav class="navbar navbar-default">
<div class="container-fluid">
<div class="navbar-header">
<a class="navbar-brand" href="index.php">Website</a>
</div>
<ul class="nav navbar-nav navbar-right">
<li><a href="index.php">Home</a></li>
<li class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">Option 1
<span class="caret"></span></a>
<ul class="dropdown-menu">
<li><a href="">Item 1</a></li>
<li><a href="">Item 2</a></li>
<li><a href="">Item 3</a></li>
</ul>
</li>
<li class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">Option 2
<span class="caret"></span></a>
<ul class="dropdown-menu">
<li><a href="">Item 1</a></li>
<li><a href="">Item 2</a></li>
<li><a href="">Item 3</a></li>
</ul>
</li>
</div>
</nav>
