Question

我创建了一个带折叠子菜单的垂直下拉菜单。

HTML：

<h2>Navigation dropdown with unfold effect</h2>
<ul class="navigation">
    <a class="main" href="#url">Menu 1</a>
    <li class="n1"><a href="#">item #1</a></li>
    <li class="n2"><a href="#">item #2</a></li>
    <li class="n3"><a href="#">item #3</a></li>
    <li class="n4"><a href="#">item #4</a></li>
    <li class="n5"><a href="#">item #5</a></li>
</ul>
<ul class="navigation">
    <a class="main" href="#url">Menu 2</a>
    <li class="n1"><a href="#">item #1</a></li>
    <li class="n2"><a href="#">item #2</a></li>
    <li class="n3"><a href="#">item #3</a></li>
    <li class="n4"><a href="#">item #4</a></li>
</ul>

CSS：

.navigation {
  list-style: none;
  padding: 0;
  width: 250px; 
  height: 40px; 
  margin: 5px auto;
  background: #95C11F;

  z-index: 100;
}

.navigation, .navigation a.main {
  border-radius: 4px;

有没有办法将第二个子菜单浮动到上一个展开菜单的末尾？

Answer 1

您可以更改菜单结构。示例http://jsfiddle.net/2e5YQ/

.menu {
   list-style:none;}
.menu li {
    position:relative;}
.menu li:hover .drop-down {
    left: 0px;
    position:relative;
}
.drop-down {
    left: -9999px;
    position:absolute;
}

<ul class="menu">
<li>Menu 1  
    <ul class="drop-down">
        <li>One</li>
        <li>Two</li>
        <li>Three</li>
    </ul>
</li>
<li>Menu 2
    <ul class="drop-down">
        <li>One</li>
        <li>Two</li>
        <li>Three</li>
    </ul>
</li>

但是这种类型的菜单并不是很有用，因为当您在下拉菜单中向下移动鼠标时，单击主菜单下拉菜单的第二个元素正在关闭，菜单的第二个元素上升非常不舒服。
