如何使推特引导菜单下拉悬停而不是点击

我想有我的引导菜单自动下拉悬停，而不是必须点击菜单标题。我还想去掉菜单标题旁边的小箭头。

当前回答

内联使用两个链接。用下拉按钮隐藏链接，并在可见链接上添加onmouseover事件以单击下拉菜单。

<a class="pretty-button"
   href="#" alt="Notifications"
   onmouseover="$('#notifications-dropdown').click()">
</a>

<a style="display:none"
   id="notifications-dropdown"
   class="js-nav js-tooltip js-dynamic-tooltip"
   href="#"
   alt="Notifications"
   data-toggle="dropdown">
   <span class="fa fa-flag fa-2x"></span>
</a>

其他回答

我们看到，除了“My Head Hurts”的答案，“Cory Price”还发现了两个问题:

问题1:单击下拉链接将打开下拉菜单。它会一直打开，除非用户点击某个地方 或者返回到它上面，创建一个尴尬的UI。 解决方案:从导航链接中删除“class”和“data-toggle”元素

这个解决方案近乎完美，但这里的问题是，当涉及到移动设备和平板电脑时，它就行不通了!

我使用了一些jQuery代码来修复这个问题..

if ($(window).width() > 769) {
    $('.dropdown-toggle').removeAttr('data-toggle');
    $('.dropdown-menu').removeAttr('style');
    $('.dropdown').removeClass('open');
}
$(window).resize(function () {
    if ($(window).width() > 769) {
        $('.dropdown-toggle').removeAttr('data-toggle');
        $('.dropdown-menu').removeAttr('style');
        $('.dropdown').removeClass('open');
    }
    else {
        $('.dropdown-toggle').attr("data-toggle", "dropdown");
    }
});

注意:这里我们假设移动设备和平板电脑的折痕从768px开始。

这适用于WordPress Bootstrap:

.navbar .nav > li > .dropdown-menu:after,
.navbar .nav > li > .dropdown-menu:before {
    content: none;
}

这里是JSFiddle -> https://jsfiddle.net/PRkonsult/mn31qf0p/1/

底部的JavaScript部分是真正起作用的部分。

HTML

<!--http://getbootstrap.com/components/#navbar-->
<div class="body-wrap">
  <div class="container">
    <nav class="navbar navbar-inverse" role="navigation">
      <div class="container-fluid">

CSS

/* Bootstrap dropdown hover menu */

body {
  font-family: 'PT Sans', sans-serif;
  font-size: 13px;
  font-weight: 400;
  color: #4f5d6e;
  position: relative;
  background: rgb(26, 49, 95);
  background: -webkit-gradient(linear, left top, left bottom, color-stop(0%, rgba(26, 49, 95, 1)), color-stop(10%, rgba(26, 49, 95, 1)), color-stop(24%, rgba(29, 108, 141, 1)), color-stop(37%, rgba(41, 136, 151, 1)), color-stop(77%, rgba(39, 45, 100, 1)), color-stop(90%, rgba(26, 49, 95, 1)), color-stop(100%, rgba(26, 49, 95, 1)));
  filter: progid: DXImageTransform.Microsoft.gradient(startColorstr='#1a315f', endColorstr='#1a315f', GradientType=0);
}

.body-wrap {
  min-height: 700px;
}

.body-wrap {
  position: relative;
  z-index: 0;
}

.body-wrap: before,
.body-wrap: after {
  content: '';
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  z-index: -1;
  height: 260px;
  background: -webkit-gradient(linear, left top, left bottom, color-stop(0%, rgba(26, 49, 95, 1)), color-stop(100%, rgba(26, 49, 95, 0)));
  background: linear-gradient(to bottom, rgba(26, 49, 95, 1) 0%, rgba(26, 49, 95, 0) 100%);
  filter: progid: DXImageTransform.Microsoft.gradient(startColorstr='#1a315f', endColorstr='#001a315f', GradientType=0);
}

.body-wrap:after {
  top: auto;
  bottom: 0;
  background: linear-gradient(to bottom, rgba(26, 49, 95, 0) 0%, rgba(26, 49, 95, 1) 100%);
  filter: progid: DXImageTransform.Microsoft.gradient(startColorstr='#001a315f', endColorstr='#1a315f', GradientType=0);
}

nav {
  margin-top: 60px;
  box-shadow: 5px 4px 5px #000;
}

JavaScript代码的重要部分:

$('ul.nav li.dropdown').hover(function() {
  $(this).find('.dropdown-menu').stop(true, true).delay(200).fadeIn(500);
}, function() {
  $(this).find('.dropdown-menu').stop(true, true).delay(200).fadeOut(500);
});

这招对我很管用:

.dropdown:hover .dropdown-menu {
    display: block;
}

还有CSS

.dropdown {
    float: left;
    padding-right: 1px;
}

.dropbtn{
    border: 0px;
    height: 30px;
    border-radius: 0px 10px;
}
li button, .dropbtn {
    display: inline-block;
    color: white;
    text-align: center;
}

li button:hover, .dropdown:hover .dropbtn {
    background-color: #12A5F4;
}

.dropbtn.active {
    background: #12A5F4;
}

.dropdown-content {
    display: none;
    position: absolute;
    background-color: #e8f3f4;
    min-width: 100%;
    box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.1);
    z-index: 10;
}

.navbar-header{
    overflow: visible;
    z-index: 1;
}

.dropdown-content a {
    color: black;
    padding: 5px 10px;
    display: block;
    text-align: left;
