我在使用下拉菜单时遇到问题。当导航的内容根据其宽度和菜单项相互堆叠的情况进行换行时,此时子菜单出现在距它一定距离处,并在我悬停之前消失。帮助!我正在处理这段代码。小提琴链接如下。
<nav>
<ul>
<li><a href="#">Home</a></li>
<li><a href="#">Menu1</a>
<ul>
<li><a href="#">Option1</a></li>
<li><a href="#">Option2</a></li>
<li><a href="#">Option3</a>
<ul>
<li><a href="#">Sub-option1</a></li>
<li><a href="#">Sub-option2</a></li>
</ul>
</li>
</ul>
</li>
<li><a href="#">Menu2</a>
<ul>
<li><a href="#">Option1</a></li>
<li><a href="#">Option2</a></li>
</ul>
</li>
<li><a href="#">Menu3</a></li>
</ul>
CSS:

display: none;
