我在桌面视图中有一个菜单，该菜单效果很好，但是如果用户将光标停留在菜单上并且几秒钟不动，那么一旦他们再次移动光标进行选择，菜单就会消失并且用户必须再次选择它。用户单击菜单后，无论如何将其悬停在菜单上多长时间（无论是否处于休眠状态），如何将菜单保留在那里。仅当用户单击栏，主页（菜单按钮）或fa fa-angle down时，它才真正消失，即使它们不再徘徊。
在移动设备视图中可以。

Css：
li#menu-item-2952 a {
background-color: unset!important;
}
ul.dropdown-menu li a {
color: black!important;
}
li#menu-item-2952 a:hover {
background-color: white!important;}
我在猜..
ul.dropdown-menu li a: hover {
then-what??}
此外，也许a不应存在，因为菜单空间也应该是可悬停的。
