我正在构建一个站点，但我遇到了这个问题......当我将鼠标悬停在 li 元素上并显示子菜单时，我无法点击其中的任何内容，因为它关闭得非常快:/我发现类似的这里已经有问题和解决方案，尝试实现它们但没有成功:/(JSFiddle Link; http://jsfiddle.net/qbNLN/1 )

HTML代码:

<ul class="main_navigation" role="menubar">
<li role="menuitem">
    <a href="#" class="link">Compre por Marcas</a>
    <div class="balloon balloon_big">
        <span class="balloon_top" style="left: 38px;"></span>
        <p class="base-title"><strong>Compre por Marcas</strong></p>
        <div class="menucolumns">
            <div class="column1">
                <ul class="submenuitems column1">
                    <li><a href="#" title="4 Plus Nutrition">4 Plus Nutrition</a></li>
                </ul>

纯 CSS 解决方案: Fiddle

使用 .main_navigation>li:hover .balloon 而不是 .main_navigation>li a:hover + .balloon，即使鼠标悬停在气球上也能确保气球保持打开状态。

然后添加，

.balloon:before {
    display: block;
    content: "";
    width: 100%;
    height: 10px;
    position: absolute;
    top: -10px;
    left: 0;
}

在菜单和气球之间添加一个不可见的 block 。
