# Different tocdepth for main toc and in-section toc

Having code like this

\documentclass{article}
\usepackage{lipsum}
\usepackage{titletoc}
\begin{document}
\tableofcontents
\section{A long section}
\startcontents[section]
\printcontents[section]{}{2}{\setcounter{tocdepth}{3}}
\lipsum[1-2]
\subsection{SubA}
\subsubsection{SSub-a}
\subsection{SubB}
\subsubsection{SSub-b}
\subsection{SubC}
\end{document}


I want to skip sub- and subsubsections for section A long section in a main TOC but have them present in a section toc. Wrapping the section with \addtocontents{toc}{\setcounter{tocdepth}{1}} and \addtocontents{toc}{\setcounter{tocdepth}{3}} hides A long section's structure from main toc but makes it's own toc disappear completely. How can I get what I want?

By default, titletoc writes partial ToCs to a file with extension .ptc; you can then set the tocdepth counter to the appropriate values (for the main ToC using \addtocontents{toc}{...} and for the partial ToC using using \addtocontents{ptc}{...}.)

\documentclass{article}
\usepackage{lipsum}
\usepackage{titletoc}
\begin{document}
\tableofcontents
\section{A long section}
\startcontents[section]
\lipsum[1-2]
\subsection{SubA}
\subsubsection{SSub-a}
\subsection{SubB}
\subsubsection{SSub-b}
\subsection{SubC}
\end{document}

great! that's exactly what i wanted –  qdiesel Jun 16 '12 at 20:29
And would it be possible to have one global tableofcontents for the sections only, then one partial tableofcontents for the subsections only, and finally one partial tableofcontents for subsubsections only? –  pluton Aug 15 '13 at 3:52
@pluton yes; it's possible using \startcontents[...], \resumecontents[...]. Perhaps you could ask this in a new question? –  Gonzalo Medina Aug 15 '13 at 14:02

In response to my own comment on Gonzalo's post, a slight modification to his solution works with the mathtools and mhchem package:

\startcontents[section]
\printcontents[section]{}{2}{\setcounter{tocdepth}{3}}


Note the only change from the MWE above is that I have removed \addcontents{ptc} and the extra set of curly braces from setcounter in the \printcontents command.

I have used this solution both in an article and a book documentclass with no problems.
