Make two-columned list start at same line as its section

Question

Following this: Make list start at same line as its section I now have two columns, instead of four, but things don't work out, see for yourself (you can get res at CV in Latex):

\documentclass[margin,line]{res}
\usepackage[inline]{enumitem}
\setlist[itemize]{leftmargin=*}

\usepackage{multicol}

\begin{document}

    Combine the good characteristics from both approaches; I want the first list to start at the same height as ``Languages".

    \section{\sc Languages}
    \begin{multicols}{2}
        \begin{itemize}[leftmargin=*]
            \item English (C2)
            \item German (B1)
            \item Italian (A1)
            \item Greek (native)
        \end{itemize}
    \end{multicols}

    Other solution, which does that, but doesn't vertically align the li's and minimizes the space between the two lines, which is ugly.
    \section{\sc Languages}
    \begin{itemize*}[leftmargin=*,itemjoin={\quad}]
        \item English (C2)
        \item German (B1) \\   % I break the line here
        \item Italian (A1)
        \item Greek (native)
    \end{itemize*}
\end{document}

and the output:

Any idea on how to tackle this?

Answer 1

Here is a solution with tasks. If you want sections tobe in small caps, you can redefine \sectionfont in the preamble. Note the syntax \sc, \bf, it is deprecated and should be replaced with the switches \scshape, \bfseries, \itshape or the commands \textsc{…}, \textbf{…}, \textit{…}.

\documentclass[margin,line]{res}
\usepackage[inline]{enumitem}
\setlist[itemize]{leftmargin=*}
\def\sectionfont{\scshape}

 \usepackage{tasks}

\begin{document}

    Combine the good characteristics from both approaches; I want the first list to start at the same height as ``Languages".

    \section{Languages}
     \begin{tasks}[label = \textbullet,  after-item-skip = 0.5ex plus 0.5ex](2)
        \task English (C2)
        \task German (B1) %
        \task Italian (A1)
        \task Greek (native)
    \end{tasks}
\end{document}
