在CSS的父级旁边放置子级菜单

Question

我有一个工作正常的菜单，但我想在它上面添加一个新的子版本，如果我直接放置，当新选项显示它们隐藏了菜单的选项时。

这里有一张图片http://www.potrusmaximus.uphero.com/dudas/menu.jpg

我希望新选项显示在选定的旁边不显示下方。 THX

这是我的CSS和Html。

Answer 1

如果你愿意，我可以修复子菜单设计，但总的来说，这就是你要找的东西吗？

#menu-bar ul ul
{
    top: 0;
    left: 100%;
}

#menu-bar li:hover > ul
{
    display: block;
}
