恢复内部枚举环境而不显示外部枚举环境的标签？

我正在使用enumitem具有以下自定义列表的包：

\newlist{answers}{enumerate}{2}
\setlist[answers,1]{label=(\alph*), ref=(\alph*)}
\setlist[answers,2]{label=(\roman*), ref=(\alph{answersi}.\roman*)}

其目的是列出评估问题的答案。我也有类似的答案。它通常用于编写嵌套问题，例如：

Here are my answers:

\begin{answers}
    \item First answer
    \item Second answers:
    \begin{answers}[series=innerlist]
        \item Answer Two-One
        \item Answer Two-Two
    \end{answers}
\end{answers}

Something I need to exit for

\begin{answers}[resume, start=2]
    \item \begin{answers}[resume=innerlist]
        \item Answer Two-Three
        \item Answer Two-Four
    \end{answers}
    \item Answer Three
\end{answers}

我希望恢复的外部列表从 (b) 恢复，但不显示标签，这样看起来好像列表从未中断，内部列表继续正常。我以为使用\item[]就可以了，但是，尽管这会隐藏该项目的标签，但它会继续下一个项目为 (b)，而不是 (c)。

可以这样做吗？我找不到有关这种情况的任何帖子，也没有在 enumitem 手册中找到任何内容。

编辑：我忘了说我知道我可以在恢复环境中执行以下操作：

\begin{answers}
    \item[] \begin{answers}[resume=innerlist]
        \item Answer Two-Three
        \item Answer Two-Four
    \end{answers}
    \setcounter{answersi}{2}
    \item Answer Three
\end{answers}

这是唯一方法/首选方法吗，或者有没有办法使用环境选项？

为了正确地恢复两者，内部和外部列表，您还应该命名series外部列表：

\documentclass{article}

\usepackage{enumitem}
\newlist{answers}{enumerate}{2}
\setlist[answers,1]{label=(\alph*), ref=(\alph*)}
\setlist[answers,2]{label=(\roman*), ref=(\alph{answersi}.\roman*)}

\begin{document}
Here are my answers:

\begin{answers}[series=outerlist]
    \item First answer
    \item Second answers:
    \begin{answers}[series=innerlist]
        \item Answer Two-One
        \item Answer Two-Two
    \end{answers}
\end{answers}

Something I need to exit for

\begin{answers}[resume=outerlist]
    \item[]\begin{answers}[resume=innerlist]
        \item Answer Two-Three
        \item Answer Two-Four
    \end{answers}
    \item Answer Three
\end{answers}

\end{document}

在您的情况下，它甚至可以在不命名外部列表的情况下工作，仅start一起使用resume没有多大意义（示例扩展为没有相同的计数器值来恢复内部和外部列表）：

\documentclass{article}

\usepackage{enumitem}
\newlist{answers}{enumerate}{2}
\setlist[answers,1]{label=(\alph*), ref=(\alph*)}
\setlist[answers,2]{label=(\roman*), ref=(\alph{answersi}.\roman*)}

\begin{document}
Here are my answers:

\begin{answers}
    \item First answer
    \item Second answers:
    \begin{answers}[series=innerlist]
        \item Answer Two-One
        \item Answer Two-Two
        \item Answer Two-Three
        \item Answer Two-Four
    \end{answers}
\end{answers}

Something I need to exit for

\begin{answers}[resume]
    \item[]\begin{answers}[resume=innerlist]
        \item Answer Two-Five
        \item Answer Two-Six
    \end{answers}
    \item Answer Three
\end{answers}

\end{document}

但是，如果您更喜欢使用start值，请使用正确的值。因此，如果第一个自动编号的项目应该是 c，请使用 3（因为它是字母表中的第三个字母）：

\documentclass{article}

\usepackage{enumitem}
\newlist{answers}{enumerate}{2}
\setlist[answers,1]{label=(\alph*), ref=(\alph*)}
\setlist[answers,2]{label=(\roman*), ref=(\alph{answersi}.\roman*)}

\begin{document}
Here are my answers:

\begin{answers}
    \item First answer
    \item Second answers:
    \begin{answers}[series=innerlist]
        \item Answer Two-One
        \item Answer Two-Two
    \end{answers}
\end{answers}

Something I need to exit for

\begin{answers}[start=3]
    \item[]\begin{answers}[resume=innerlist]
        \item Answer Two-Three
        \item Answer Two-Four
    \end{answers}
    \item Answer Three
\end{answers}

\end{document}

结果与第一个例子所示相同。
