问题

是否可以将\item命令保留在主体中，并使用包中的命令包装itemize列表环境？我还尝试将列表包装在 TikZ 节点中，该节点也包装在\NewEnvironenvironminipage:) 中，我知道这是可能的这里。

目的

保持源代码尽可能简单。

示例代码

\documentclass{article}
\usepackage{fontspec}
\usepackage{tikz}
\usetikzlibrary{calc,positioning}
\usepackage{environ} % \NewEnviron command collects body and can be accessed by \BODY macro within the definition for making custom environments

\NewEnviron{RedBoxList}[1][MISSING VARIABLE!]{%
    \begin{tikzpicture}[remember picture, overlay]
        \path [fill=red] (current page.north west) rectangle (current page.north);
        \node [xshift=5mm,yshift=-10mm,anchor=north west, align=left] (nodeID) at (current page.north west) {%
            \begin{minipage}[t]{.6\linewidth}
                \textcolor{white}{%
                    {\Huge #1}
                    \begin{itemize}
                        \BODY
                    \end{itemize}
                }% end textcolor white
           \end{minipage}
        };% end node
    \end{tikzpicture}
}% end NewEnviron

\begin{document}
\begin{RedBoxList}{Title of the Box}
    \item test1 
    \item test2
    \item test3
\end{RedBoxList}
\end{document}

答案1

你正在定义RedBoxList使用选修的参数，不是强制性的，所以

\begin{RedBoxList}[Title of the Box]
    \item test1 
    \item test2
    \item test3
\end{RedBoxList}

将会做你想让它做的事。

但是，它似乎是一个糟糕的用户界面：忘记可选参数将导致标题为“缺少变量！”，因此最好将此参数作为必需的进行管理：

 \NewEnviron{RedBoxList}[1]{%
   <same code as before>
 }

答案2

您需要声明Title of The Box参数。我将其更改为[2]这意味着它不使用可选参数#1，但我不知道您打算将其用于何处

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{calc,positioning}
\usepackage{environ} % \NewEnviron command collects body and can be accessed by \BODY macro within the definition for making custom environments

\NewEnviron{RedBoxList}[2][MISSING VARIABLE!]{%
    \begin{tikzpicture}[remember picture, overlay]
        \path [fill=red] (current page.north west) rectangle (current page.north);
        \node [xshift=5mm,yshift=-10mm,anchor=north west, align=left] (nodeID) at (current page.north west) {%
            \begin{minipage}[t]{.6\linewidth}%\show\BODY
                \textcolor{white}{%
                    {\Huge #2}
                    \begin{itemize}
                        \BODY
                    \end{itemize}
                }% end textcolor white
           \end{minipage}
        };% end node
    \end{tikzpicture}
}% end NewEnviron

\begin{document}
\begin{RedBoxList}{Title of the Box}
    \item test1 
    \item test2
    \item test3
\end{RedBoxList}
\end{document}
