将 mdframed 环境应用于自定义列表环境

Question

我想将mdframed环境应用到list如下描述的自定义环境中这里，稍作修改并如下所示。

我想在环境的每个调用周围放置一个框架（可破坏）category。之所以需要框架，只是因为我试图模仿电子可填写表格的样式。

请参阅以下 MWE 和支持文件：

\documentclass{article}
\usepackage[]{geometry}
\usepackage{lipsum}
%\usepackage{mdframed}

\input{required_code.tex}

\newenvironment{category}[1]{%
    \begin{list}{}{%
    \parsep\parskip%
    \setlength{\itemsep}{-\parsep}%
    }\item {\bfseries \section{#1}
    }%
    \nobreakitem%
    }%
    {\end{list}}%
\begin{document}

\begin{category}{First Category}
\lipsum[1-4]
\end{category}

\begin{category}{Second Category}
\lipsum[5-10]
\end{category}

\end{document}

并且 required_code.tex 看起来像：

  \@inmatherr\nobreakitem
  \@ifnextchar [\@nobreakitem{\@noitemargtrue \@nobreakitem[\@itemlabel]}}
