对编辑后的查询的回复

我想将一个 itemize 环境用括号括起来，并将其括在 itemize 环境里面。

\documentclass[a4paper]{article}
 \usepackage{enumitem}
 \usepackage{pifont}
\begin{document}
\begin{itemize}[label=\ding{42}, leftmargin=2cm]
   \item  Example I
   \item Example II
        \begin{itemize}
                    \left. 
                          \begin{array}{ll}
        \item SubExample II-1
        \item SubExample II-2
                          \end{array}
                      \right \}=Text
         \end{itemize}
    \item Example III
    \item Example IV
                \end{itemize}
\end{document}

有没有办法在 itemize 环境中做到这一点

请问 Harish Kumar 教授，在这种情况下，对于长文本和短文本以及反之亦然，我该怎么做，如下所示：

\documentclass[a4paper]{article}
\usepackage{tikz,xparse}
\usetikzlibrary{decorations.pathreplacing,}
\newcommand{\tikzmark}[1]{\tikz[baseline={(#1.base)},overlay,remember picture] \node[outer sep=0pt, inner sep=0pt] (#1) {\phantom{A}};}

%% syntax
%%%\mybrace{<first>}{<second>}[<Optional text>]
\NewDocumentCommand\mybrace{mmo}{%
\IfValueTF {#3}{%
\begin{tikzpicture}[overlay, remember picture,decoration={brace,amplitude=1ex}]
  \draw[decorate,thick] (#1.north east) -- (#2.south east) node[midway, right=0.1cm] {$=$}node[midway, right=0.5cm,text=black,text width = 2in,] {{#3}};
\end{tikzpicture}%
}%
{%
\begin{tikzpicture}[overlay, remember picture,decoration={brace,amplitude=1ex}]
  \draw[decorate,thick] (#1.north east) -- (#2.south east);
\end{tikzpicture}%
}%
}%

\begin{document}
\begin{itemize}
   \item  Example I
   \item Example II
        \begin{itemize}
        \item long text bla bla bla\tikzmark{a}
        \item short text bla\tikzmark{b}
         \end{itemize}
    \item Example III
    \item Example IV
\end{itemize}
\mybrace{a}{b}[Text comes here to describe these to items and justify for your case]

\end{document}

像这样？

\documentclass[a4paper]{article}
\usepackage{tikz}
\usetikzlibrary{decorations.pathreplacing,}
\newcommand{\tikzmark}[1]{\tikz[baseline={(#1.base)},overlay,remember picture] \node[outer sep=0pt, inner sep=0pt] (#1) {\phantom{A}};}

\begin{document}
\begin{itemize}
   \item  Example I
   \item Example II
        \begin{itemize}                    
        \item SubExample II-1\tikzmark{a}
        \item SubExample II-2\tikzmark{b}
         \end{itemize}
    \item Example III
    \item Example IV
\end{itemize}
\begin{tikzpicture}[overlay, remember picture,decoration={brace,amplitude=2pt}]
  \draw[decorate,thick] (a.north east) -- (b.south east) node[midway, right=0.1cm] {$=$}node[midway, right=0.5cm,text=black,text width = 2in,] {Text comes here to describe these to items and justify for your case};
\end{tikzpicture}%
\end{document}

使用宏

如果您最终需要多次使用它，您可以制作一个宏。

\documentclass[a4paper]{article}
\usepackage{tikz,xparse}
\usetikzlibrary{decorations.pathreplacing,}
\newcommand{\tikzmark}[1]{\tikz[baseline={(#1.base)},overlay,remember picture] \node[outer sep=0pt, inner sep=0pt] (#1) {\phantom{A}};}

%% syntax
%%%\mybrace{<first>}{<second>}[<Optional text>]
\NewDocumentCommand\mybrace{mmo}{%
\IfValueTF {#3}{%
\begin{tikzpicture}[overlay, remember picture,decoration={brace,amplitude=1ex}]
  \draw[decorate,thick] (#1.north east) -- (#2.south east) node[midway, right=0.1cm] {$=$}node[midway, right=0.5cm,text=black,text width = 2in,] {{#3}};
\end{tikzpicture}%
}%
{%
\begin{tikzpicture}[overlay, remember picture,decoration={brace,amplitude=1ex}]
  \draw[decorate,thick] (#1.north east) -- (#2.south east);
\end{tikzpicture}%
}%
}%

\begin{document}
\begin{itemize}
   \item  Example I
   \item Example II
        \begin{itemize}
        \item SubExample II-1\tikzmark{a}
        \item SubExample II-2\tikzmark{b}
         \end{itemize}
    \item Example III
    \item Example IV
\end{itemize}
\mybrace{a}{b}[Text comes here to describe these to items and justify for your case]

\end{document}

这里我们做一些假设：

  1. 子项的长度可以变化
  2. 但它们足够短，不会跨越多行（因为如果跨越多行，那么描述就变得毫无意义）

基于这些假设，你可以将子 itemize 环境放入minipage宽度等于0.5\textwidth环境中。您可以根据需要改变此宽度。

\begin{itemize}
   \item  Example I
   \item Example II
      \begin{minipage}[t]{0.5\textwidth}
        \begin{itemize}
        \item SubExample II-1 just more length\tikzmark{a}
        \item SubExample II-2\hfill\tikzmark{b}
         \end{itemize}
      \end{minipage}
    \item Example III
    \item Example IV
\end{itemize}
\mybrace{a}{b}[Text comes here to describe these to items and justify for your case]

另一个选择是将每个子项放在\parbox宽度为的范围内0.5\textwidth：

\documentclass[a4paper]{article}
\usepackage{tikz,xparse}
\usetikzlibrary{decorations.pathreplacing,}
\newcommand{\tikzmark}[1]{\tikz[baseline={(#1.base)},overlay,remember picture] \node[outer sep=0pt, inner sep=0pt] (#1) {\phantom{A}};}

%% syntax
%%%\mybrace{<first>}{<second>}[<Optional text>]
\NewDocumentCommand\mybrace{mmo}{%
\IfValueTF {#3}{%
\begin{tikzpicture}[overlay, remember picture,decoration={brace,amplitude=1ex}]
  \draw[decorate,thick] (#1.north east) -- (#2.south east) node[midway, right=0.1cm] {$=$}node[midway, right=0.5cm,text=black,text width = 2in,] {{#3}};
\end{tikzpicture}%
}%
{%
\begin{tikzpicture}[overlay, remember picture,decoration={brace,amplitude=1ex}]
  \draw[decorate,thick] (#1.north east) -- (#2.south east);
\end{tikzpicture}%
}%
}%

\begin{document}
\begin{itemize}
   \item  Example I
   \item Example II \par
      %\begin{minipage}{0.5\textwidth}
        \begin{itemize}
        \item \parbox[t]{0.5\textwidth}{SubExample II-1 just more length as they come here}\tikzmark{a}
        \item \parbox{0.5\textwidth}{SubExample II-2}\tikzmark{b}
         \end{itemize}
%      \end{minipage}
    \item Example III
    \item Example IV
\end{itemize}
\mybrace{a}{b}[Text comes here to describe these to items and justify for your case]

\end{document}
