Question

嗨，我试图创建一个导航栏，当你悬停李另一个列表从侧面出来显示其他选项。我的问题我可以与第一个李对齐，但我不知道如何与列表的其余部分一起做。目前，下拉列表保持在同一位置。

我确定我没有充分解释这里是我的代码。

<body class="menu">
<header>
    <nav class="menu-side">
    <ul>
              <li class="icon-home"><a href="Premiership.html"><span>Home</span></a></li>

            <li class="arrow"> <a  class="star" href="#">England</a>
                <ul>
                    <li><a class="ee" href="Premiership.html">Premiership</a>
                    </li>
                    <li><a href= "Unavailble.html">Championship</a>
                    </li>
                    <li><a href="Unavailble.html">League 1</a>
                    </li>
                    <li><a href="Unavailble.html">League 2</a>
                    </li>
                </ul>
            </li>
            <li class="arrow"> <a  href="#">France</a>
                <ul >
                    <li id="r"><a class="ee" href="Unavailble.html">Ligue 1</a> 
                    </li>
                </ul>
            </li>

Answer 4

查看此更新的JSFiddle。将li设置为position: relative;，将ul ul设置为position: absolute。在那里，您可以将ul ul＆＃39; left设置为100%。这会将它们一直推到父级的右侧。在悬停时，您可以使用left: calc(100% + 5px)来计算li的白色右边框。不需要凌乱的利润。

无法将子菜单与父项对齐
