所以我试图从列表项中配置一个简单的下拉列表,但我不能在我的生活中找出为什么当我将鼠标悬停在列表项上时它不会停止覆盖列表项。这是html:

<div class="dropdown" style="float:right">
                <li><a class="active dropbtn" href="">Profile</a></li>
                <div class="dropdown-content">
                <a href="#">Link 1</a>
                <a href="#">Link 2</a>
                <a href="logout.php?logout"><span class="glyphicon   glyphicon-log-out"></span>&nbsp; Logout</a></a>
                </div>
            </div>

这样做的风格是:

tr:hover {background-color: #f5f5f5}
th, td {
padding: 15px;
text-align: left;
}

/* The container <div> - needed to position the dropdown content */
.dropdown {
position: relative;
}

/* Dropdown Content (Hidden by Default) */
.dropdown-content {
display: none;
position: absolute;
background-color: #f9f9f9;
min-width: 160px;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
z-index: 10;
}

/* Links inside the dropdown */
.dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
}

/* Change color of dropdown links on hover */
.dropdown-content a:hover {background-color: #f1f1f1}

/* Show the dropdown menu on hover */
.dropdown:hover .dropdown-content {
display: block;
}

/* Change the background color of the dropdown button when the dropdown     content is shown */
.dropdown:hover .dropbtn {
background-color: #3e8e41;

除此之外,尽管更改了下拉元素的z-index,但我无法将菜单显示在父列表所在的菜单之外

感谢所有帮助

            <div class="dropdown-content">
            <a href="#">Link 1</a>

            <a href="logout.php?logout"><span class="glyphicon   glyphicon-log-out"></span>&nbsp; Logout</a>
            </div>

CSS看起来很好。
