在此示例中，如何使用\breakbox强制下面定义的示例环境在新页面上继续？
这里有一个例子来说明：
\begin{document}
\maketitle
\section{test}
\begin{exemple}
\LR{Example!}
$$
\vdots
$$
\breakbox
$$
\vdots
$$
\LR{How can I force this box to start on a new page?
}
\end{exemple}
\end{document}
输出如下：
以下是模板中环境的定义：
%%%%%%%%%%% Environnement "exemple"
\newsavebox{\ex@box}
\newenvironment{exemple}[1][]
{%
\setcounter{break@box}{0}
\setcounter{type@box}{1}
\typebox{ex}
\def\titletext{مثال}
\ifx#1\@empty\xdef\pluriel@ex{}\else\xdef\pluriel@ex{#1}\fi
\itemclass{extitle@bg@color}{\extitle@font}
\begin{lrbox}{\ex@box}
\begin{minipage}{\dimexpr\linewidth-\marginleft}
}
{%
\end{minipage}
\end{lrbox}
\vspace*{\spacebeforeex}
\begin{tikzpicture}
\node[fill=ex@bg@color] (texte) {\usebox{\ex@box}};
\node[fill=extitle@bg@color,text=extitle@color,below right,draw=extitle@bg@color,very thick,text width={\dimexpr\marginleft-2mm},align=center] at ($(texte.north east)+(0pt,0)$) { \large\bf\titletext\pluriel@ex \ifnum\thebreak@box>0\par(suite)\fi};
\end{tikzpicture}
}

我在它们之间添加了 \par，并且另一个框会自动打印在另一页上，以防我感兴趣。
该解决方案基于@John Kormylo 的提示
