Varias cajas con muchas filas en una línea con envoltura cuando se desborda

Question

Me gustaría tener varias cajas con muchas filas en una línea y envolverlas cuando las cajas se desbordan.

La idea sería crear un entorno personalizado para contribuyentes/revisores que también pueda usar con TeX4ht:

\documentclass[a4paper]{report}

\usepackage{pgffor}

\newcommand{\ccReviewer}[1]{%
    \hbox{#1}
}
\newcommand{\ccAffiliation}[1]{%
    \hbox{#1}
}
\newcommand{\ccReviewersList}[1]{%
    \hbox{%
        \foreach \reviewer / \affiliation in #1{%
            \vbox{
                \ccReviewer{\reviewer}%
                \ccAffiliation{\affiliation}
            }
        }
    }
}


\begin{document}
\begin{center}
    {\large Contributors and Reviewers}\\
    \vspace{5mm}
    \def\ccReviewers{%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation%
    }
    \ccReviewersList{\ccReviewers}
\end{center}

\end{document}

Aquí está la salida actual:

\documentclass[a4paper]{report}

\usepackage{pgffor,stackengine}

\newcommand{\ccReviewer}[1]{%
    \hbox{#1}
}
\newcommand{\ccAffiliation}[1]{%
    \hbox{#1}
}
\newcommand{\ccReviewersList}[1]{%
        \foreach \reviewer / \affiliation in #1{%
            \Longstack[l]{%
                \ccReviewer{\reviewer}
                \ccAffiliation{\affiliation}
            }
        }
}
\begin{document}
\begin{center}
    {\large Contributors and Reviewers}\\
    \vspace{5mm}
    \def\ccReviewers{%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation%
    }
    \ccReviewersList{\ccReviewers}
\end{center}
\end{document}

Podrías simplificarlo aún más:

\documentclass[a4paper]{report}

\usepackage{pgffor,stackengine}

\newcommand{\ccReviewersList}[1]{%
    \foreach \reviewer / \affiliation in #1{%
        \addstackgap[4pt]{\Longstack[l]{\reviewer{} \affiliation}}\hspace{4pt} 
    }
}
\begin{document}
\begin{center}
    {\large Contributors and Reviewers}\\
    \vspace{5mm}
    \def\ccReviewers{%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation%
    }
    \ccReviewersList{\ccReviewers}
\end{center}
\end{document}

...o incluso reemplazar pgfforcon listofitems, como tal, permitiéndole no requerir los %trailers en la \ccReviewerslista:

\documentclass[a4paper]{report}

\usepackage{stackengine,listofitems}

\newcommand{\ccReviewersList}[1]{%
    \setsepchar[?]{,?/}%
    \readlist*\authlist{#1}%
    \foreachitem\x\in\authlist[]{%
        \addstackgap[4pt]{%
        \Longstack[l]{\authlist[\xcnt,1] \authlist[\xcnt,2]}}\hspace{4pt}
    }
}
\begin{document}
\begin{center}
    {\large Contributors and Reviewers}\\
    \vspace{5mm}
    \def\ccReviewers{
        Author/Affiliation,
        Author/Affiliation,
        Author/Affiliation,
        Author/Affiliation,
        Author/Affiliation,
        Author/Affiliation,
        Author/Affiliation,
        Author/Affiliation,
        Author/Affiliation,
        Author/Affiliation,
        Author/Affiliation
    }
    \ccReviewersList{\ccReviewers}
\end{center}
\end{document}
