In the following MWE I would like to have automatically the labels of items shaped in bold and the colons added instead of being typed.
\documentclass[12pt]{article}
\usepackage{enumitem}
\begin{document}
\begin{itemize}
\item[ALG :]
méthode de type ALG-ébrique
\item[ARI :]
méthode de type ARI-thmétique
\item[GÉO :]
méthode de type GÉO-métrique
\end{itemize}
\end{document}
\begin{itemize}[font=\bfseries]
Alternatively, you might be interested indescription
instead ofitemize
. For a description list with automatically added colons, take a look at this answer: tex.stackexchange.com/a/238763/134144
