因此，当我从下拉列表中选择菜单项时，它会在加载链接时消失。我已经验证菜单项设置为显示在所有页面上。这是css设置吗？谢谢

它可以在这里：

/* All menu links on hover or focus */
#nav a:hover, #nav a:focus, #subMenusContainer a:hover, #subMenusContainer a:focus, #nav a.mainMenuParentBtnFocused, #subMenusContainer a.subMenuParentBtnFocused{
    background-color:#3366FF ;
    color:#FFF;  /* Try #AAF here  */
}

/* sub menu links on hover or focus */
#subMenusContainer a:hover, 
#subMenusContainer a:focus, 
#nav a.mainMenuParentBtnFocused, 
#subMenusContainer a.subMenuParentBtnFocused,
#nav li a:hover,
#nav li a:focus{
    background-color:#3366FF ;
    color:#FFF; /* Try #AAF here  */
}

这个 CSS 使文本的颜色变为白色。这里的背景不是白色，而是在您background:#fff;应用的 CSS 之后#nav ul。

如果这不起作用，您需要发布您的 html、制作小提琴或发布实时链接。
