Listing Chapter/Section/Subsection numbers with the preview

Question

After compiling all the content of the book, I use Adobe reader to preview the content. Note that the legend that I use to navigate through the book (the listing on the left (usually) with the option '+' on which one clicks, and it offers the content) only contains the Chapter/Section/Subsection names. How could I change this to include the numbering, i.e, such that the legend contains, e.g., '3 Chapter name' with '+' sign, and it opens to, e.g. '3.1 Section name'... I hope you understand what I'm asking.

Answer 1

You can use the bookmarksnumbered option for hyperref or the numbered option for bookmark:

\documentclass{book}
\usepackage[bookmarksnumbered]{hyperref}

\begin{document}
\chapter{Test}
\section{Test section}
\end{document}

or

\documentclass{book}
\usepackage[numbered]{bookmark}

\begin{document}
\chapter{Test}
\section{Test section}
\end{document}

Answer 2

Add option bookmarksnumbered to the hyperref call (or use \hypersetup{bookmarksnumbered})
