Vertically aligning list bullet when using \infer

Question

I have a list where one of the list items is an \infer{...}{...} command. In this case, the list bullet is not vertically centered with the item, as you can see in the picture:

How can I move the list bullet at the height of the bar?

MWE

\documentclass{scrreprt}
\usepackage{proof}
\linespread{1.5}
\begin{document}
\begin{itemize}
\item item 1
\item item 2
\item \infer{Something}{Something else}
\end{itemize}

\end{document}

Answer 1

You can use the \vcenter box command, which centers its contents (just above) the baseline. It is used for big operators etc. and requires you to be in maths mode.

\documentclass{scrreprt}

\usepackage{proof}
\linespread{1.5}

\begin{document}

\begin{itemize}
\item item 1
\item item 2
\item \( \vcenter{\infer{\textit{Something}}{\textit{Something else}}} \)
\end{itemize}

\end{document}
