此问题与Menu Component :
有关我修改了代码,以便在悬停而不是点击时打开菜单。我点击菜单中的某些元素内部时,我现在试图让菜单保持打开或关闭。但是我无法让它工作。
有人可以帮忙吗?

示例:
<li class="wont-close">
后,菜单不会关闭。 menu.show();
<li class="will-close">
后,菜单将关闭。 menu.hide();

如有疑问,请创建纯CSS解决方案......
我不接受我的答案为 答案 ,因为这是一个黑客攻击。
我只想在此处包含此内容,以显示我执行完全相同操作的快速修复(直到
cubic-bezier
动画)。注意:我还在使用它附带的材料设计样式 ......只是没有任何JS。
