Question

我有这个网站：http://dev.gratefulhearttherapy.org/ 使用下拉菜单，当您悬停“我们的服务”或“Abous Us”等类别时，它应该展开。但事实并非如此。

我知道这是一个CSS问题，因为我使用了两种不同的样式表，一种是有效的，另一种则没有。但是我花了两个小时才发现它并没有找到什么问题。

我尝试使用z-index但它不起作用。我接管了别人的工作，CSS文件很乱，网站调用了几个样式表。无论如何，我正在使用的样式表在这里：http://dev.gratefulhearttherapy.org/index.php/tools/css/themes/gratefulheart/typography-new2.css

CSS的相关部分开始第287行，即“Mega Menu”部分。这是：

任何人都可以向我提一下可能存在的问题吗？

Answer 1

这是因为您的#headerNav设置为overflow:hidden。只需删除这行css：

#headerNav {
    …
    overflow: hidden;
    …    
}

CSS：下拉菜单不显示
