我正在使用导航菜单的一系列提交按钮（提交值将是整个站点的导航方法）。我从下拉菜单中创建了一个带有弹出窗口的下拉菜单。但是，我无法弄清楚如何仅隔离下拉框中的悬停元素以显示它的弹出窗口。所有下拉菜单项都显示所有子菜单或无。我曾尝试在不同区域使用>和+子选择器。任何人都可以帮忙吗？如何仅在类列表中选择一个孩子
我的CSS：
/* Dropdown Button */
.ddb-container {
width: 100%;
overflow: hidden;
background-color: #faebca;
font-family: Arial;
margin-top: 75px;
padding-left: 150px;
z-index: 1;
border-top: 3px black solid;
border-bottom: 3px black solid;
border-left: none;
border-right: none;
}
.ddb-container button {
margin: 0;
padding: 0;
float: left;
font-size: 14px;
border: none;
color: #000000;
text-align: center;
padding: 5px 10px;
text-decoration: none;
font-weight: bold;
background-color: transparent;
}
.ddb-container button:hover {
background-color: #dbcfa4;
}
.ddb-dropdown {
float: left;
overflow: hidden;
font-size: 14px;
font-weight: bold;
}
.ddb-dropdown .dropbtn {
border: none;
outline: none;
color: #000000;
padding: 5px 10px;
background-color: transparent;
}
.ddb-dropdown .dropbtn:hover {
background-color: #dbcfa4;
}
.ddb-dropdown .dropdown-level1 {
display: none;
position: absolute;
background-color: #faebca;
min-width: 160px;
box-shadow: 0px 8px 12px 0px rgba(0,0,0,0.2);
z-index: 1;
}
.ddb-dropdown:hover .dropdown-level1 {
display: block;
}
.ddb-dropdown .dropdown-level1 .dropdown-level2 {
display: none;
position: absolute;
background-color: #faebca;
min-width: 160px;
margin-left: 160px;
box-shadow: 0px 8px 12px 0px rgba(0,0,0,0.2);
z-index: 2;
}
.ddb-dropdown .dropdown-level1:hover .dropdown-level2 {
display: block;
}

我会更好地显示，呈现给浏览器的HTML，所以我们并不需要从你的PHP –
重新创建它谢谢你，乔恩。我编辑它显示HTML –
不是说这会解决您的问题，但为什么使用'button'而不是'a'来链接？ 'a'被设计用于链接。另外使用'br'作为间隔是一种不好的做法，在CSS中使用'margin'代替。 –
