我的 WordPress 网站上的菜单出现在多个页面的内容后面的问题。 iv 一直在网上寻找解决方案，并且 iv 查看了 z-index 并一直在使用不同的值来应用，但仍然没有成功。
如果有任何帮助，我将不胜感激

最佳答案
在#main-navigation > .sf-menu > ul类中添加一个正的z-index，将使下拉菜单出现在页面内容的前面.
#main-navigation > .sf-menu > ul {
position: absolute;
top: 0;
left: 0;
width: 100%;
max-height: 0;
max-width: 16em;
overflow: hidden;
background: #333;
}
会变成
#main-navigation > .sf-menu > ul {
position: absolute;
top: 0;
left: 0;
width: 100%;
max-height: 0;
max-width: 16em;
overflow: hidden;
background: #333;
z-index: 999;
}
