如何在附加转义事件后重置自定义下拉菜单以显示菜单？
How to reset a custom dropdown to display the menu after escape event attached?
我有一个自定义下拉菜单。除了一个区域，我已经能够处理大部分的可访问性。当菜单打开并且我按下退出键时，如果我使用键盘导航回该菜单，我将无法返回该菜单。
此外，class 之前的伪码在我按下转义键时不会被删除。我不确定如何定位那个伪 class.
如果该菜单已导航回，我该如何将其恢复？

此外，class 之前的伪码在我按下转义键时不会被删除。我不确定如何定位那个伪 class.
如果该菜单已导航回，我该如何将其恢复？
