Update: a previous version of this question wrongly attributed the problem to use of minitoc to get section-level tables of contents (\secttoc).

I've got a complicated document with a tables of content, and which switches between one and two-column mode.

I'd like to remove the subsection headings themselves from the text, but leave them in the TOCs.

I tried the recipe from this answer:

\newcommand{\nosubsection}[1]{%
\refstepcounter{subsection}%
\markright{#1}}


This almost works, but the TOCs comes out wrong. I.E.,

1 first section
1.1 first sub
1.1.1 first subsub
1.1.2 second subsub
1.2.1 first subsub    % <--- WRONG
1.2 second sub


but should really be

1 first section
1.1 first sub
1.1.1 first subsub
1.1.2 second subsub
1.2 second sub
1.2.1 first subsub


I think this is due to a strange interaction with the switching between one- and two-column mode: the first subsubsection in each subsection are put in the subsection above where they belong. This happens even when I just to include the supposedly do-nothing \onecolumn\twocolumn.

Here's an MWE (or actually, a minimal failing example):

\documentclass[11pt]{article}
\newcommand{\nosubsection}[1]{%
\refstepcounter{subsection}%
\markright{#1}}

\begin{document}
\tableofcontents

\section{first section---show all subs 1---works}
\subsection{first sub 1.1}
\twocolumn[{\subsubsection{first subsub 1.1.1}}]
\twocolumn[{\subsubsection{second subsub 1.1.2}}]
\subsection{second sub 1.2}
\twocolumn[{\subsubsection{first subsub 1.2.1}}]

\section{second section--don't show subs 2 --- fails}
\nosubsection{first sub 2.1} %\label{sub:2.1}
\twocolumn[{\subsubsection{first subsub 2.1.1}}]
\twocolumn[{\subsubsection{second subsub 2.1.2}}]
\onecolumn  %%%% these casuse the problem, I think
\twocolumn
\nosubsection{second sub 2.2}
\twocolumn[{\subsubsection{first subsub 2.2.1 \textbf{WRONG}}}]

\end{document}


(Note that you need both nosubsection and column-switching to get the failure.)

I have also tried using the multicol package, and I get the same problem.

Any ideas?

• Welcome to TeX.SX! Please add a minimal working example (MWE) starting with \documentclass{...} and ending with \end{document} to help us reproduce your problem. – Pier Paolo Feb 9 '15 at 16:12
• @PierPaolo, yes, thanks for the admonition. The very fact that I can't do that easily implies that the problem is some ugly interaction between the macros in my document (I suspect includeonly and import, but I can't trace it very far. Aaargh! – Andrew Jaffe Feb 9 '15 at 17:55
• @PierPaolo: much changed now (just adding comment so that you notice it -- sorry!) – Andrew Jaffe Feb 10 '15 at 13:42
• Please, make a sensible example: \onecolumn immediately followed by \twocolumn means nothing. – egreg Feb 10 '15 at 14:20
• @egreg: this is the minimal working example. Feel free to insert any text between those; it will still fail! – Andrew Jaffe Feb 10 '15 at 14:22

The relevant part of the \subsection heading is (see macro \@sect in latex.ltx for example)

\begingroup
#6{%
\@hangfrom{\hskip #3\relax\@svsec}%
\interlinepenalty \@M #8\@@par}%
\endgroup


If this should not appear when the section level is subsection, it could be patched to use a \ifstrequal for testing if #1 is equal to subsection.

I added the \begin{multicols}{2}...\end{multicols} wrappers as well.

\documentclass[11pt]{article}
\usepackage{multicol}
\usepackage{blindtext}
\usepackage{xpatch}

\makeatletter
\xpatchcmd{\@sect}{%
\begingroup
#6{%
\@hangfrom{\hskip #3\relax\@svsec}%
\interlinepenalty \@M #8\@@par}%
\endgroup
}{%
\ifstrequal{#1}{subsection}{%
% Do nothing here!
}{%
\begingroup
#6{%
\@hangfrom{\hskip #3\relax\@svsec}%
\interlinepenalty \@M #8\@@par}%
\endgroup
}%
}{\typeout{successful patching}}{\typeout{Nope}}
\makeatother
