答案 1 :(得分：0)

您只需增加子菜单的z-index即可。添加

.nav ul ul{
  z-index:99;
}
  

z-index属性指定元素的z顺序及其顺序   后人。当元素重叠时，z顺序决定哪一个   涵盖了另一个。具有较大z指数的元素通常覆盖一个   较低的元素。

虽然在这种情况下99的值可能过大，但z-index有效地决定了相关元素的分层优先级。请注意，为了应用，该元素还需要position集（您的子菜单已经存在）

答案 2 :(得分：0)

添加

.content{
    z-index: -100;
}

内容就像成为下拉菜单项的叠加层。所以光标活动范围就丢失了。

或为菜单

添加正值的z-index
