.wrapper-dropdown-2:after {

我试着将鼠标悬停在：登录，打开下拉菜单但不起作用！我不能与js合作。因为我有1.8.2的问题，但我认为我们可以找到一个CSS

的解决方案

Answer 1

试试这个

.wrapper-dropdown-2:hover ul{
    display:block;  
}

updated jsFiddle File

同时删除.dropdown：悬停你的风格

Answer 2

您将丢失添加悬停代码，以便在悬停时看到下拉列表。添加css悬停。

.wrapper-dropdown-2:hover .dropdown
{
    display:block;
}

Live Demo

Answer 3

您需要初始化您的javascript以及链接到jquery。我看到你正在使用Codrops的下拉列表，为什么不下载源代码？

Answer 4

只需替换您的CSS

.dropdown:hover  {
  /* Size & position */
    position: absolute;
    display:block;
    top: 100%;
    left: -5px;
    right: 0px;

    /* Styles */
    background: white;
    -webkit-transition: all 0.3s ease-out;
    -moz-transition: all 0.3s ease-out;
    -ms-transition: all 0.3s ease-out;
    -o-transition: all 0.3s ease-out;
    transition: all 0.3s ease-out;
    list-style: none;

    /* Hiding */
    opacity: 0;
    pointer-events: none;
}

到我的CSS并获得结果

.wrapper-dropdown-2:hover > .dropdown  {
   position: absolute;
    display:block;
    left: -45px;
       background: white;
      top:24px;
 }

CSS下拉列表悬停鼠标不起作用
