# Enumerated list in subsubsection style

How can I define a list environment using a package like enumitem such that it reproduces the same output as the following code but with the syntax of an enumerated list:

\documentclass[a4paper,12pt]{article}

\usepackage{lipsum}

\begin{document}

\subsubsection*{Item 1}
\lipsum[1]

\subsubsection*{Item 2}
\lipsum[2]

\subsubsection*{Item 3}
\lipsum[3]

%% The following syntax should produce the same as above.

% \begin{mylist}
%   \item
%     \lipsum[1]
%   \item
%     \lipsum[2]
%   \item
%     \lipsum[3]
% \end{mylist}

\end{document}


Desired output:

• Shall Item 1 etc. be printed as well? – user31729 Aug 21 '16 at 11:18
• Yes, exactly as in the output of the posted example. – student Aug 21 '16 at 11:22
• Using \subsubsection* is easier then, in my point of view – user31729 Aug 21 '16 at 11:34
• @ChristianHupfer You mean something like this: tex.stackexchange.com/a/176265/4011 – student Aug 21 '16 at 11:57
• Yes, pretty much like that. – user31729 Aug 21 '16 at 11:59

Here is a possibility

\documentclass[a4paper,12pt]{article}
\usepackage{lipsum}
\usepackage{calc}
\usepackage[inline]{enumitem}
\newlist{mylist}{enumerate}{1}
\setlist[mylist]{
label=\bfseries Item \arabic*,
labelwidth=\widthof{last-item},
leftmargin=!,
align=left,
itemindent=1.8cm,
itemsep=10pt
}

\newcommand{\myitem}{\item~\\[6pt]}
\begin{document}
\subsubsection*{Item 1}
\lipsum[1]

\subsubsection*{Item 2}
\lipsum[2]

\subsubsection*{Item 3}
\lipsum[3]

%% The following syntax should produce the same as above.

\begin{mylist}
\myitem
\lipsum[1]
\myitem
\lipsum[2]
\myitem
\lipsum[3]
\end{mylist}

\end{document}


I had to redefine \item too so to send the item text to a new line.

labelwidth=\widthof{last-item},
leftmargin=!,
align=left,


are for setting the label next to the margin. To automatically calculate the largest label width the package calc is needed.

itemindent=1.8cm,


is for removing the indent of the item text (this is the only value I wasn't able to compute automatically but should be fixed, so not a big deal)

itemsep=10pt


sets the vertical space between items

\newcommand{\myitem}{\item~\\[6pt]}


sends the item text to a newline with a vertical space of 6pt from the label.

• Actually you did not redefine \item, you wrapped in another macro ;-) Hopefully \myitem[...] is never requested ;-) – user31729 Aug 21 '16 at 11:42
• @ChristianHupfer oh yes, you are absolutely right! – Nico Boni Aug 21 '16 at 11:45

A very simple code, which lets you use the usual \item command:

\documentclass[a4paper,12pt]{article}
\usepackage{lipsum}
\usepackage{enumitem}
\newlist{mylist}{enumerate}{1}

\setlist[mylist]{label=\raisebox{0pt}[4ex][3ex]{\makebox[\textwidth][l]{\bfseries Item \arabic*}}, wide = 0pt}

\begin{document}

\begin{mylist}
\item
\lipsum[1]
\item
\lipsum[2]
\item
\lipsum[3]
\end{mylist}

\end{document}
