基本上我有一个并排的水平菜单，你可以在这里看到：http://www.supplements-today.co.uk/walnutgarth3/availability.php
我想要做的是让'onhover'有一个子菜单可以降低某些选项，例如'pictures'。我可以在这里看到我的尝试：http://www.supplements-today.co.uk/walnutgarth3/
现在我已经让下拉部分工作了，但是如你所见，它会破坏我菜单其余部分的风格。对我来说问题是'
任何人都知道我的问题在这里？你可以在pagesource中看到我的菜单代码，但到目前为止，我的css是：
#tier1 div{ display:none; }
#tier1{
position: relative;
left: 70px;
height: 20px;
}
#tier2{
position: relative;
display: block;
}
我知道那是空的，但iv用各种各样的方式玩弄，似乎无法让它发挥作用。任何帮助非常感谢：）

尝试使用一些JQuery菜单插件。 JQuery被广泛使用，并且有很多通过互联网浏览菜单的例子。 其中一个例子可以找到here.
