Question

我正在尝试创建一个CSS3悬停菜单，该菜单会过渡并在其下方显示子菜单。我遇到的问题是我无法将子菜单放在彼此之下。目前，我有这种效果 - http://jsfiddle.net/7pz3g/1/

这是HTML标记 -

<nav id="navbar">
    <ul class="iconContainer">
        <li>
            <a href="/"><i class="fa fa-home fa-lg"></i></a>
            <ul id="wrapperFirst" class="extMenu">
                <li><h3>Testing</h3></li>
                <li>SubMenu
                    <ul id="wrapperSecond" class="subMenu">
                        <li><h3>ORGANIZATIONS</h3></li>
                        <li><a href="http://reddit.com/‎">Reddit</a></li>
                    </ul>
                </li>
            </ul>
        </li>
    </ul>
</nav>

CSS MarkUp -

li {
    list-style: none;
}

#navbar {
    background-color: #333333;
    position: fixed;
    text-align: center;

#wrapperSecond.subMenu h3 {
    text-align: center;
}

#wrapperSecond.subMenu .subtitle {
    font-family: 'SourceSansProRegular';
    font-size: .6em;
}

#wrapperSecond.subMenu li a {
    text-decoration: none;
    color: #75A4C7;
    line-height: 40px;
    font-size: 1em;
    text-shadow: 1px 1px 1px #000;
}

#wrapperSecond.subMenu li {
    padding: 10px 20px;
    text-align: left;
    height: auto;
    text-decoration: none;
    line-height: 40px;
    font-size: 1em;
    text-shadow: 1px 1px 1px #000;
    color: white;
    opacity: 1;
    border-bottom: 1px solid rgba(255, 255, 255, .2);
    cursor: pointer;
}

#wrapperSecond.subMenu li {
    opacity: 1;
}

#wrapperSecond.subMenu {
    width: 600px;
    opacity: 1;
}

#wrapperSecond.subMenu h3 {
    text-align: center;
}

#wrapperSecond.subMenu .subtitle {
    font-family: 'SourceSansProRegular';
    font-size: .6em;
}

#wrapperSecond.subMenu li a {
    text-decoration: none;
    color: #75A4C7;
    line-height: 40px;
    font-size: 1em;
    text-shadow: 1px 1px 1px #000;
}

我希望将每个子菜单转换到其根菜单下方，但仍然保持在页面上的其他元素之上。有任何想法吗？感谢!!!
