Two-column beamer ToC with control over the breaking point

Question

From Splitting TOC into two columns on single frame in beamer, I'd like to know whether it is possible to control the position of the breaking point between column 1 and column 2?

Answer 1

Apparently, \addtocontents also works with the beamer class. Use \newpage (not \clearpage!) to force a column break.

\documentclass{beamer}

\usepackage{multicol}

\begin{document}

\begin{frame}{\contentsname}
\begin{multicols}{2}
\tableofcontents
\end{multicols}
\end{frame}

\section{bla}
\begin{frame}{bla}
Some text.
\end{frame}

\section{blubb}
\begin{frame}{blubb}
Some text.
\end{frame}

\section{foo}
\begin{frame}{foo}
Some text.
\end{frame}

\addtocontents{toc}{\newpage}

\section{bar}
\begin{frame}{bar}
Some text.
\end{frame}

\end{document}

Answer 2

An excellent solution has been posted here:

https://tex.stackexchange.com/a/136082/113639

\begin{frame}
    \frametitle{Outline}
    \begin{columns}[t]
        \begin{column}{.5\textwidth}
            \tableofcontents[sections={1-3}]
        \end{column}
        \begin{column}{.5\textwidth}
            \tableofcontents[sections={4-5}]
        \end{column}
    \end{columns}
\end{frame}

As you can see, the break points are manual here (using the sections= parameter). Furthermore, this solution avoids all the vertical alignment problems of the other multicols solutions I have seen here so far, where the second column would often not start at the top.
