我们设置了twitter bootstrap下拉列表来处理悬停（而不是点击[是的，我们知道没有悬停在触摸设备上]）。但是我们希望能够在点击它时使主链接工作。
默认情况下，twitter bootstrap会阻止它，那么我们如何重新启用呢？

只需在您的主播上添加已禁用作为课程：
<a class="dropdown-toggle disabled" href="http://google.com">
Dropdown <b class="caret"></b></a>
所有这些都像：
<ul class="nav">
<li class="dropdown">
<a class="dropdown-toggle disabled" href="http://google.com">
Dropdown <b class="caret"></b>
</a>
<ul class="dropdown-menu">
<li><a href="#">Link 1</a></li>
<li><a href="#">Link 2</a></li>
</ul>
</li>
</ul>
答案 1 :(得分：11)
对于那些抱怨“子菜单不下降”的人，我这样解决了，看起来很干净：
1）除了你的
<a class="dropdown-toggle disabled" href="http://google.com">
Dropdown <b class="caret"></b>
</a>
换上新的
<a class="dropdown-toggle"><b class="caret"></b></a>
并删除<b class="caret"></b>标记，因此它看起来像
<a class="dropdown-toggle disabled" href="http://google.com">
Dropdown</a><a class="dropdown-toggle"><b class="caret"></b></a>
2）使用以下css规则对它们进行设置：
.caret1 {
position: absolute !important; top: 0; right: 0;
}
.dropdown-toggle.disabled {
padding-right: 40px;
}
.caret1类中的样式用于将其绝对定位在右侧角落的li内。
第二种方式是在下拉列表的右侧添加一些填充以放置插入符号，防止重叠菜单项的文本。
现在你有一个很好的响应式菜单项，它在桌面和移动版本中看起来都不错，并且可点击和可下载，具体取决于你是单击文本还是插入符号。
答案 2 :(得分：10)
由于没有真正的答案可行（选择的答案禁用下拉列表），或使用javascript覆盖，这里就是。
这是所有html和css修复（使用两个<a>标记）：
<ul class="nav">
<li class="dropdown dropdown-li">
<a class="dropdown-link" href="http://google.com">Dropdown</a>
<a class="dropdown-caret dropdown-toggle"><b class="caret"></b></a>
<ul class="dropdown-menu">
<li><a href="#">Link 1</a></li>
<li><a href="#">Link 2</a></li>
</ul>
</li>
</ul>
现在这里是你需要的CSS。
.dropdown-li {
display:inline-block !important;
}
.dropdown-link {
display:inline-block !important;
padding-right:4px !important;
}
.dropdown-caret {
display:inline-block !important;
padding-left:4px !important;
}
假设您希望两个<a>标记在悬停任何一个时突出显示，您还需要覆盖bootstrap，您可以使用以下内容：
.nav > li:hover {
background-color: #f67a47; /*hover background color*/
}
.nav > li:hover > a {
color: white; /*hover text color*/
}
.nav > li:hover > ul > a {
color: black; /*dropdown item text color*/
}
答案 3 :(得分：4)
我不确定将顶级锚点元素设置为可点击锚点的问题，但这是使桌面视图具有悬停效果的最简单解决方案，以及保持其点击能力的移动视图。
// Medium screens and up only
@media only screen and (min-width: $screen-md-min) {
// Enable menu hover for bootstrap
// dropdown menus
.dropdown:hover .dropdown-menu {
display: block;
}
}
这样，移动菜单仍然可以正常运行，而桌面菜单会在悬停时展开，而不是点击。
答案 4 :(得分：2)
另一种解决方案是从锚点中删除“dropdown-toggle”类。此单击后将不再触发dropwon.js，因此您可能希望在悬停时显示子菜单。
答案 5 :(得分：1)
您可以使用javascript snippit

这是一个根据屏幕宽度从数据悬停切换到数据切换的小黑客：
/**
* Bootstrap nav menu hack
*/
$(window).on('load', function () {
// On page load
if ($(window).width() < 768) {
$('.navbar-nav > li > .dropdown-toggle').removeAttr('data-hover').attr('data-toggle', 'dropdown');
}
// On window resize
$(window).resize(function () {
if ($(window).width() < 768) {
$('.navbar-nav > li > .dropdown-toggle').removeAttr('data-hover').attr('data-toggle', 'dropdown');
} else {
$('.navbar-nav > li > .dropdown-toggle').removeAttr('data-toggle').attr('data-hover', 'dropdown');
}
});
});

这可以通过添加两个链接来简化，一个包含text和href，另一个包含下拉列表和插入符号：
<a href="{{route('posts.index')}}">Posts</a>
<a href="{{route('posts.index')}}" class="dropdown-toggle" data-toggle="dropdown" role="link" aria-haspopup="true" aria- expanded="false"></a>
<ul class="dropdown-menu navbar-inverse bg-inverse">
<li><a href="{{route('posts.create')}}">Create</a></li>
</ul>
现在，您点击下拉列表和链接作为链接。不需要css或js。 我使用 Bootstrap 4 4.0.0-alpha.6 ，定义插入符号是不必要的，它出现时没有html。
