我正在使用bootstrap 3用于桌面,并且只使用导航而不是导航栏.
如何在悬停上下拉并点击？

<ul id="nav" class="nav nav-pills clearfix right" role="tablist">
    <li><a href="#">menuA</a></li>
    <li><a href="#">menuB</a></li>
    <li class="dropdown"><a href="#" class="dropdown-toggle" data-toggle="dropdown">menuC</a>
        <ul id="products-menu" class="dropdown-menu clearfix" role="menu">
            <li><a href="">A</a></li>
            <li><a href="">B</a></li>
            <li><a href="">C</a></li>
            <li><a href="">D</a></li>
        </ul>
    </li>
