Question

我有一个我正在研究的移动网站。我终于得到了JS代码，用于显示单击而不是悬停的子菜单。现在我无法直接在主菜单下定位子菜单。我研究了最好的，我发现我需要使主菜单位置“相对”和子菜单“绝对”。我一直在试图解决这个问题，但没有运气。代码有点乱，请原谅我。我只是个菜鸟。

Answer 1

尝试更改HTML，以便在第一个li的中间没有div结尾。

然后，如果您将ID直接放在隐藏菜单上，您可以使用javascript直接隐藏/显示隐藏菜单

/* Changed this so that your hidden menu is hidden by default */
.smenu_div li ul
{ 
  display: none;
  position: relative;
  width: 100%;
  background: transparent;

.smenu_div ul li a
