[Tex/LaTex] Create new \subsubsubsection in custom class file

documentclass-writingsectioningsections-paragraphstable of contents

I've copied the default article.cls file and made some very minor alterations mainly to the \listoftables and \listoffigures titles, which is not connected to my question.

I'd like to add 1 extra level in between \subsubsection and \paragraph. This new section would push down \paragraph and \subparagraph down one level to make room for the new \subsubsubsection to be insert at level 4.

Microsoft Word comes with 9 headings which aren't inline headings, whilst I don't require that many at the moment, I do require the first 4 to not be inline headings and additional two headings as paragraph inline heading should be sufficient for my needs.

This section would appear fairly similar to \subsubsection in that it would be a heading on it's own line and not how the \paragraph command works with having the content on the same line as the heading.

I'm not using \paragraph or \subparagraph in my report for that reason. But am needing a 1.1.1.1 Section in my report and on my contents page.

There is a solution on this site that looked like what I was trying to achieve, but I was unable to get it to work from within my custom class file.

Just use \paragraph but style paragraph to be a display rather than a run-in header. That is far easier than implementing a whole new section level:

\documentclass{article}

\makeatletter
%same as \subsubsection but level 4
\renewcommand\paragraph{\@startsection{paragraph}{4}{\z@}%
                                     {-3.25ex\@plus -1ex \@minus -.2ex}%
                                     {1.5ex \@plus .2ex}%
                                     {\normalfont\normalsize\bfseries}}
% number \paragraph
\setcounter{secnumdepth}{4}

\makeatother

\begin{document}

\section{zzz}
\subsection{zzz}
\subsubsection{zzz}
\paragraph{zzz}
aaa
\end{document}

You can use the titlesec package to change the way \paragraph formats the titles and set the secnumdepth counter to four to obtain numbering for the paragraphs:

\documentclass{article}
\usepackage{titlesec}

\setcounter{secnumdepth}{4}

\titleformat{\paragraph}
{\normalfont\normalsize\bfseries}{\theparagraph}{1em}{}
\titlespacing*{\paragraph}
{0pt}{3.25ex plus 1ex minus .2ex}{1.5ex plus .2ex}

\begin{document}

\section{Test Section}
test
\subsection{Test Subsection}
test
\subsubsection{Test Subsubsection}
test
\paragraph{Test Modified Paragraph}
test

\end{document}

If you want to define a new sectioning command, you can take a look at Defining custom sectioning commands.

If you want to define a fresh new sectional unit below \subsubsection, but above \paragraph, then you will have to do considerably more work: a new counter has to be created and its representation has to be appropriately defined; the sectional units \paragraph and \subparagraph will also have to be redefined, as well as they corresponding \l@... commands (controlling how the will be typeset in the ToC if the tocdepth value is increased); also, the toclevel (for eventual bookmarks) will have to be considered.

Here's an example showing how to obtain this new sectional unit giving you now the option to use \part, \section, \subsection, \subsubsection, \subsubsubsection, \paragraph, and \subparagraph:

\documentclass{article}
\usepackage{titlesec}
\usepackage{hyperref}

\titleclass{\subsubsubsection}{straight}[\subsection]

\newcounter{subsubsubsection}[subsubsection]
\renewcommand\thesubsubsubsection{\thesubsubsection.\arabic{subsubsubsection}}
\renewcommand\theparagraph{\thesubsubsubsection.\arabic{paragraph}} % optional; useful if paragraphs are to be numbered

\titleformat{\subsubsubsection}
  {\normalfont\normalsize\bfseries}{\thesubsubsubsection}{1em}{}
\titlespacing*{\subsubsubsection}
{0pt}{3.25ex plus 1ex minus .2ex}{1.5ex plus .2ex}

\makeatletter
\renewcommand\paragraph{\@startsection{paragraph}{5}{\z@}%
  {3.25ex \@plus1ex \@minus.2ex}%
  {-1em}%
  {\normalfont\normalsize\bfseries}}
\renewcommand\subparagraph{\@startsection{subparagraph}{6}{\parindent}%
  {3.25ex \@plus1ex \@minus .2ex}%
  {-1em}%
  {\normalfont\normalsize\bfseries}}
\def\toclevel@subsubsubsection{4}
\def\toclevel@paragraph{5}
\def\toclevel@paragraph{6}
\def\l@subsubsubsection{\@dottedtocline{4}{7em}{4em}}
\def\l@paragraph{\@dottedtocline{5}{10em}{5em}}
\def\l@subparagraph{\@dottedtocline{6}{14em}{6em}}
\makeatother

\setcounter{secnumdepth}{4}
\setcounter{tocdepth}{4}

\begin{document}

\tableofcontents
\section{Test Section}
test
\subsection{Test Subsection}
test
\subsubsection{Test Subsubsection}
test
\subsubsubsection{Test Subsubsubsection}
test
\paragraph{Test Paragraph}
test
\subparagraph{Test Subparagraph}
test

[Tex/LaTex] scrreprt – add levels below \subparagraph

Quoting the manual from the titlesec package:

With the help of classes you may insert, say, a new subchapter level between chapter and section, or creating a scheme of your own.

(at subsection 3.9 in the titlesec.pdf).

At appendix 9.2, it shows exactly how the already existing sections and the like are defined; don't copy the already existing parts to your file, but use them as inspiration for defining new ones (amount of indentation, style, etc). My advice is to look at all the appendices and subsection 3.9.
