javascript - 垂直展开列表标签 (li) 以在 css 的多行中动态包含文本

Question

我目前正在使用 this来自 this 的 jsfiddle片段，我正在尝试将两行文本放入列表项之一，其中“其余文本需要显示”当前处于隐藏状态。

对于我的元素，我可能需要显示超过两行的列表项，那么 css/javascipt 中是否有一种方法可以将列表环绕在文本周围

 <ul class="nav sidebar-nav">       
        <li>
            <a href="#">
                item 1<br>rest of the text need to show
            </a>
        </li>
        <li>
            <a href="#">
                item 2         
            </a>
        </li>
        <li>
            <a href="#">
                item 3

            </a>
        </li>
    </ul>

Answer 1

从 a 标签中移除固定高度，元素高度将匹配其中内容的大小。这是一个更新的 fiddle https://jsfiddle.net/0m4qdvja/5/
