DropDown Aligned

Question

我有一个下拉选项的菜单，我试图调整从列表中选择的相应项目下的下拉菜单。到目前为止，它与左侧对齐，下拉ul列表位于应显示下拉列表的元素内。

我不确定我在做什么错在这里，有一些建议？

Answer 1

添加position: relative;到#menu ul li {和left:0;到#menu ul ul将要对它进行适当低于选定。

#menu ul li { 
    display: inline; 
    position: relative; 
} 

#menu ul ul 
{ 
    display:none; 
    position:absolute; 
    top:100%; 
    left:0; 
    background: fuchsia; 
    padding:0 
}
