我创建了一个菜单和一个子菜单,当我将鼠标悬停在主菜单的列表元素上时应该会出现这些子菜单。问题是主菜单列表元素的宽度在悬停时会发生变化,看起来令人费解。我尝试了固定宽度,但是菜单项之间的空间太大了。

我还尝试将子菜单设置为绝对位置,但问题是子菜单始终位于同一位置,而不是位于活动的主菜单项下方。

我为此问题创建了一个代码笔

您可以通过将主菜单按钮设置为position: relative并将(绝对)子菜单放置在其中来将子菜单放置在主菜单按钮下方。然后,您通过切换overflow: hidden和来显示/隐藏子菜单visible

这是一个演示:http ://codepen.io/seraphzz/pen/osGnh
