Latex enumerate: making first item italic

Question

I have an enumerate-list and want to make the first item in this list (including the number) italic. It seems like I can make everything italic except the first number - otherwise the whole list crashes. Here are some minimum examples:

This one works

\documentclass[]{scrartcl}
\begin{document}
\section{Test}
\begin{enumerate}
    \item \textit{dsfdsf
    \item adsadasd}
\end{enumerate}
\end{document}

This one also

\documentclass[]{scrartcl}
\begin{document}
\section{Test}
\begin{enumerate}
    \item dsfdsf
    \textit{\item adsadasd}
\end{enumerate}
\end{document}

But this one doesn't

\documentclass[]{scrartcl}
\begin{document}
\section{Test}
\begin{enumerate}
    \textit{\item dsfdsf
    \item adsadasd}
\end{enumerate}
\end{document}

Why does the last one crash the list and what could be workarounds? Thanks!

Answer 1

First \items are processed a little differently. Rather change the font shape using a switch:

\documentclass{scrartcl}
\begin{document}
\section{Test}
\begin{enumerate}
  {\itshape\item dsfdsf}
  \item adsadasd
\end{enumerate}
\end{document}
