Question

第一个下拉列表正常工作，但第二个下拉列表根本无法正常工作。我试图指定更多的类，但不起作用，我相信这是非常简单的，我没有被注意到。如果有人帮助我，我将不胜感激。

我说的下拉菜单是＆＃34;其他游戏机＆＃34;菜单，它是用课程显示div＆＃34; dropdown-content-2＆＃34;当徘徊在＆＃34; a＆＃34;标签与＆＃34; drop-secundario＆＃34;类。

Answer 1

将上一个CSS规则的选择器更改为：

.dropdown-content a.drop-secundario:hover+.dropdown-content-2

原因是：.dropdown-content-2不是a.drop-secundario的孩子，而是其兄弟，因此＆＃34; +＆＃34;在那个选择器中。
