在 LaTeX2e 中使用超链接-package，您可以应用命令
\hyperref[⟨referencing-label⟩]{⟨tokens that form the text of the hyperlink⟩}如何才能把一个完整的\item（即，项目符号/项目编号以及项目文本）作为第一项出现在枚举环境/逐项环境中变成这样一个可点击的超链接？
我可以提供一个最小的例子，它并不完全符合我的要求：:-)
\documentclass[a4paper]{article}
\usepackage[colorlinks=true, linkcolor=red]{hyperref}

to the section ``A section''.\\
But---as expected with this approach---the

答案1
值得注意的是，\item的标签（\textbullet或 下的数字enumerate）实际上可以作为链接点击，因为它设置在零宽度框内。这是为了确保\items 上的适当右（水平）对齐。
下面的代码提供了按以下方式\hyperrefitem[<link>]{<item>}设置泛型的方法：\item
\item[{\hyperref[<link>]{<label>}}]
\hyperref[<link>]{<item>}
取决于<label>您是否使用itemize或enumerate（无论级别/深度如何。使用此方法 - 使用超链接明确设置列表标签 - 即使标签也是\item可点击的。
