# [Tex/LaTex] How to make appendices like section in bookmarks

appendicesbookmarkshyperref

I had a problem as I wanted to make my appendices look like sections.

I already found a solution to do this for the table of contents by using this code just before the \chapter command in the appendix environment :

\makeatletter
\makeatother


Now, I would like to make the bookmarks "realize" it. When I open the PDF file the Appendices appears at a chapter level, but the title of the appendix appears at chapter level too.

All the bookmarks I have come from the hyperref package, so I guess I can't use the bookmark package to find a solution.

Is there any way to make it look like a section of the chapter Appendices in the bookmarks?

Here is the code I use in my LaTeX program:

\begin{appendices}
\makeatletter
\makeatother
\chapter{Appendix1}
\chapter{Appendix2}
...
\end{appendices}


I already tried to use the \section function instead of \chapter, but it doesn't seem to work.

## Method via \bookmarksetupnext

With package bookmark the following is possible:

\bookmarksetupnext{level=-1}


overwrites the bookmark setting of "Appendices" and moves it a level higher to part level. Then the appendix chapters become children to the "part" appendices.

\documentclass{report}
\usepackage{appendix}
\usepackage{hyperref}
\usepackage{bookmark}
\begin{document}
\tableofcontents
\chapter{A chapter}
\section{A section}
\chapter{Another chapter}
\section{A section}
\begin{appendices}
\bookmarksetupnext{level=-1}
\makeatletter
\makeatother
\chapter{Appendix1}
\chapter{Appendix2}
...
\end{appendices}
\end{document}


The example is based on the example in Werner's answer.

## Method via \toclevel@<section>

Package hyperref configures the bookmark levels in macros \toclevel@chapter, \toclevel@section:

...
\def\toclevel@chapter{0}
\def\toclevel@section{1}
\def\toclevel@subsection{2}
\def\toclevel@subsubsection{3}
\def\toclevel@paragraph{4}
\def\toclevel@subparagraph{5}
...


These macros can be redefined:

\begin{appendices}
\makeatletter
\def\toclevel@chapter{1}
\def\toclevel@section{2}
\def\toclevel@subsection{3}
% ... (add deeper levels if needed)
\makeatother
\chapter{Appendix1}
\chapter{Appendix2}
...
\end{appendices}


Remark: You can use package bookmark together with hyperref getting faster updated bookmarks and more features.
