Question

我正在执行此下拉菜单，当＆＃34; aulas＆＃34;徘徊出现一个子菜单。问题是：我无法在子菜单上选择我想要的链接，因为当aulas没有悬停时它会消失。拜托，非常感谢你。

在以下规则中，将top调整为26px。

ul li ul {
padding: 0;
position: absolute;
top: 26px;
left: 0;
width: 150px;
-webkit-box-shadow: none;
-moz-box-shadow: none;
box-shadow: none;
display: none;
opacity: 0;
visibility: hidden;
}
