Question

仅在Safari中，二级菜单出现问题。顶层和子菜单在chrome，firefox等鼠标悬停时可以正常工作，但是在Safari中打开时，只有第一个菜单在悬停时打开。我已经尝试过这里和其他论坛上提供的其他解决方案，但是仍然是一样的。

.nav {
    margin: 2% 10% 0 35%;
    /*margin-bottom: 4px;
    margin-top: 2%;
    margin-left: 35%;
    margin-right: 10%;*/
    width: 60%;
    height: auto;
    z-index: 1;
    position: absolute;
}

.nav-container {
    display: inline-block;
    padding: 0;
    font-weight: 300;
    font-family:"Open Sans";
    font-size: 15px;
}

.nav-container a:hover {
    color: #FFFFFF;
}

.nav-pos {
    display: inline-block;
    padding-bottom: 15px;
}

.nav-pos-sp {
    /*padding-left: 30px;*/
    padding-left: 0px !important;
    margin-left: 30px;
}

.navbar-nav {
    margin-top: 1%;
    display: none;
    height: auto;
    color: #C7C7C7;
    width: 200px;
    overflow: hidden;
    position: fixed;
}

.navbar-nav-menu a {
    font-size: 14px;
    display: block;
    text-align: left;
    padding: 15px 0px 15px 12px;
    border-bottom: thin solid #fff;
    background-color: #343434;
}

/* child menu dropdown */
.navbar-nav-child {
    display: none;
    height: auto;
    color: #C7C7C7;
    width: 200px;
    overflow: hidden;
    position: fixed;
    margin-left: -200px;
    margin-top: -50px;
}

.navbar-nav-menu-item-101a:hover .navbar-nav-child {
        margin-left: 200px !important;
        display: block !important;
}

.navbar-nav-menu-child-text a {
        font-size: 14px;
        display: block;
        text-align: left;
        padding: 15px 0px 15px 12px;
        border-bottom: thin solid #fff;
        background-color: #2B2B2B;
}

.services:hover .navbar-nav-menu {
        display: block;
}

我已经为菜单添加了HTML和CSS代码。我还使用Windows操作系统在chrome上对其进行了检查，并且可以使用，但唯一的问题是野生动物园浏览器。

我有一些建议可能会有所帮助。

首先，我不建议使用position: fixed;来定位子菜单，因为fixed是相对于浏览器窗口的位置。您可能希望子菜单根据父窗口而不是窗口来定位。

第二，您在overflow: hidden;上有.navbar-nav，这意味着不属于其边界的任何内容-包括子菜单。

这是一个JSFiddle，其中包含您的代码片段的工作示例以及我的建议，并在Safari中进行了测试和工作：

.nav {
  margin: 2% 10% 0 35%;
  width: 60%;
  height: auto;
  z-index: 1;
  position: absolute;
}

.nav-container {
  display: inline-block;
  padding: 0;
  font-weight: 300;
  font-family: "Open Sans";
  font-size: 15px;
}

.nav-container a:hover {
  color: #FFFFFF;
}

.nav-pos {
  display: inline-block;
  padding-bottom: 15px;
}

.nav-pos-sp {}

.navbar-nav {
  margin-top: 1%;
  display: none;
  height: auto;
  color: #C7C7C7;
  width: 200px;
  position: relative;
}

.navbar-nav-menu a {
  font-size: 14px;
  display: block;
  text-align: left;
  padding: 15px 0px 15px 12px;
  border-bottom: thin solid #fff;
  background-color: #343434;
}

/* child menu dropdown */

.navbar-nav-child {
  display: none;
  height: auto;
  color: #C7C7C7;
  width: 200px;
  position: absolute;
  top: 0;
