我真的需要帮助我们尽快在我的网站上正确显示下拉子菜单。

我的下拉菜单中的子菜单相互堆叠。

我希望这些子菜单垂直显示。

我该如何解决这个问题？

这是我的代码：

div#nav_menu-2{
  	float: left!important;
}

div.menu-secondary-container{
  	display: block;
    background-color: #f3e6ff;
	background-size: cover;
	margin: 0px;
	padding: 0px;
	overflow: visible;
	position: static;
}

div#nav_menu-2 ul{
    top: 0px;
    margin: 0px;
}

div#nav_menu-2 ul li{
   	list-style-type: none;
	/*position: relative;*/
	display: inline-block;
}

div#nav_menu-2 ul li a{
  	display: block;
	padding: 14px 16px;
	text-align: center;
	line-height: 30px;
	text-decoration: none;
	font-size: 12pt;
	font-weight: bold;
	color: purple;
	text-transform: uppercase;
}

div#nav_menu-2 ul li a:hover{
	background-color: lightgray;
}

div#nav_menu-2 ul li a:active{
	background-color: hotpink;
}

div#nav_menu-2 ul li a:link{
	color: darkpurple;
}

div#nav_menu-2 ul li a:visited{
	color: lightpurple;
}

.active{
	background-color: dimgray;
}

div#nav_menu-2 ul li li{
  	display:none;
  	clear: both;
  	overflow: auto;
  	white-space: nowrap;
}

div#nav_menu-2 ul li:hover ul li{
	display: block;
    position:absolute;
   
}

div#nav_menu-2 ul li li a{
	background-color: lightgray;
	padding: 14px 16px;
	min-width: 160px;
	display: block;
	text-align: center;
}

答案 0 :(得分：2)

您错误地隐藏了子菜单<li>而不是子菜单<ul>。除此之外，您的代码主要是工作。

这是一个小提琴：https://jsfiddle.net/rkwcty1u/

您现在会注意到:hover它显示的是<ul>而不是<li>。子菜单<ul>也位于absolute，父级<li>位于relative位置，因此它正确包含它。

我已将以下代码添加到您的 CSS ，并在padding中修改了line-height和div#nav_menu-2 ul li a。

div#nav_menu-2 ul ul {
  position: absolute;
  left: 0;
  top: 40px;
}
div#nav_menu-2 ul li:hover a {
  background-color: lightgray;
}

＆＃13;
＆＃13; 
div#nav_menu-2 {
  float: left;
}
div.menu-secondary-container {
  display: block;
  background-color: #f3e6ff;
  background-size: cover;
  margin: 0px;
  padding: 0px;
  overflow: visible;
  position: relative;
}
div#nav_menu-2 ul {
  top: 0px;
  margin: 0px;
}
div#nav_menu-2 ul li {
  list-style-type: none;
  display: inline-block;
}
div#nav_menu-2 ul li a {
  display: block;
  padding: 0px 16px;
  text-align: center;
  line-height: 40px;
  text-decoration: none;
  font-size: 12pt;
  font-weight: bold;
  color: purple;
  text-transform: uppercase;
}
div#nav_menu-2 ul li a:hover {
  background-color: lightgray;
}
div#nav_menu-2 ul li a:active {
  background-color: hotpink;
}
div#nav_menu-2 ul li a:link {
  color: darkpurple;
}
div#nav_menu-2 ul li a:visited {
  color: lightpurple;
}
.active {
  background-color: dimgray;
}
div#nav_menu-2 ul li li {
  display: none;
  clear: both;
  overflow: auto;
  float: none;
  white-space: nowrap;
}
div#nav_menu-2 ul li:hover ul li {
  display: block;
}
div#nav_menu-2 ul li li a {
  background-color: lightgray;
  padding: 14px 16px;
  min-width: 160px;
  display: block;
  text-align: center;
}
div#nav_menu-2 ul ul {
  position: absolute;
  left: 0;
  top: 40px;
}
div#nav_menu-2 ul li:hover a {
