  • "选择选项"现在读成了“按钮”，实际上点击后不会有反应，建议这里不需要读成“按钮”
  • 非第一级选项列表会有一个隐藏元素能获取焦点

  • 苹果手机上切换到最后一级选项列表时无法选中

这2个问题是不是还能复现？

非第一级选项列表会有一个隐藏元素能获取焦点

关于这一点，目前实现的方式是将上一级隐藏 aria-hidden="true"，从代码来看（如下视频），是成功设置了的，但是真机测试似乎是没有设置成功，在这里记录一下。

截止目前此组件无障碍支持还遗留的问题如下：

  1. 上一层【被选中的】选项能获取焦点（点击后切换到下一层级，但上一层【被选中】的那一项还能被选中）
  2. 最后一层级，点击后无法无法关闭

因一时间未找到解决办法，所以先行合并此 pr，以完成前置支持，然后重新提一个 issue 来记录，同时也希望能有社区大佬给解决一波！
