# Correct subsection bookmarks without section

I have a bunch of "naked" subsections, i.e. not belonging to a section.

\documentclass[12pt,a4paper]{report}
\usepackage{newtxtext, newtxmath}
\usepackage{amssymb,amsmath}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{hyperref}
\hypersetup{unicode=true,
pdfborder={0 0 0},
\urlstyle{same}
\begin{document}
\chapter{First}
\subsection{Foo}
\subsection{Bar}
\subsection{Fizz}
\subsection{Buzz}

\chapter{Second}
\section{Sect}
\subsection{Foo}
\subsection{Bar}
\subsection{Fizz}
\subsection{Buzz}
\end{document}

The bookmark to the first subsection upgrades to a section bookmark, and all the rest subsection bookmarks seem to belong to this.

In the second chapter, with a section present, everything works OK. How can I have the subsection under the chapter, like this?

• Loading the bookmark package might do the job. – epR8GaYuh Apr 17 '18 at 14:59
• Perfect! Just as simple as that! Please submit this as an answer, to accept it. – Theo Apr 17 '18 at 15:33
• A subsection without parental section is no subsection and a logically and typographically ill designed – user31729 Apr 17 '18 at 20:23
