# Custom item in enumerate

I would like to have an enumerate - list in which, after 1, 2, 3, 4, I need to put 4bis.

How to do it?

• Shortest way: \item[4bis] your text ;-) – user31729 Jul 24 '15 at 12:26
• @ChristianHupfer: so easy? I know see that numbers and "4bis" are aligned on the right. Is it possible to have the 4 and 4bis aligned on the left? – enzotib Jul 24 '15 at 12:31
• Should be possible, yes – user31729 Jul 24 '15 at 12:34

Aligning the label left is easy with align=left from enumitem package. The special item can be set with \item[4bis], but this is only a strategy, if this does not occur very often.

• If the features of the enumerate package are requested, change to \usepackage[shortlabels]{enumitem} here.
• If the label should be wider, just say labelwidth=40pt, for example, in the option list of \begin{enumerate}

\documentclass{article}

\usepackage{enumitem}
\begin{document}
\begin{enumerate}[align=left]
\item One
\item Two
\item Three
\item Four
\item[4bis] Some with four again
\item Other stuff
\end{enumerate}
\end{document}
