html - 双下拉-带重载的第三列列表

我一直在尝试找出如何为我的双下拉菜单添加一个“溢出”列。 （所有CSS）我仅使用“娱乐”链接这是现场直播示例：http://www.glustik.com/dustreeproductions/company.php“ Solos | Duos | Trios”显然太长，是一个问题。我正在尝试将10左右的所有列出的项目“溢出”到另一列（尚未显示）。关于如何完成此操作的任何帮助或建议将非常有帮助，并始终受到赞赏。感谢Guys（和女士们）这是我的CSS导航：

最佳答案

为什么不使用现有ID定位有问题的ul并将其扩大呢？

 #solos ul{width: 575px;}

正如您已经浮动了li的左侧一样，当您扩展ul的宽度以使其适合两个li时，它们将以两行换行。

您还需要更改此规则：

#nav > li ul li:hover ul {
    display: block;
    left: 280px;
    padding: 0 10px 0 5px;
    position: absolute;
    top: 0;
    width: 305px; /* Delete this */
}
