List of frames displayed in multicolumn

Question

Is there a way to display the list of frames in multicolumns (2 or 3). I use the following code from the following post [Is there any way to produce List of frames with beamer?

\documentclass{beamer}
\beamertemplatenavigationsymbolsempty
\usepackage{verbatim}
\usepackage{hyperref}

\newif\ifframeinlbf
\frameinlbftrue
\makeatletter
\newcommand\listofframes{\@starttoc{lbf}}
\makeatother

\addtobeamertemplate{frametitle}{}{%
  \ifframeinlbf
  \addcontentsline{lbf}{section}{\protect\makebox[2em][l]{%
    \protect\usebeamercolor[fg]{structure}\insertframenumber\hfill}% 
  \protect\hyperlink{page.\insertpagenumber}\insertframetitle\par}
  \else\fi
}
\begin{document}
\frameinlbffalse
\begin{frame}[fragile,t,allowframebreaks]
\frametitle{List of Frames}
\listofframes
\end{frame}
\frameinlbftrue
\begin{frame}
\frametitle{Frame 1}
frame 1
\end{frame}
\begin{frame}
\frametitle{Frame 2}

\end{frame}
\begin{frame}

\end{frame}
\begin{frame}

\end{frame}
\begin{frame}

\end{frame}
\begin{frame}

\end{frame}
\begin{frame}

\end{frame}
\begin{frame}

\end{frame}
\begin{frame}

\end{frame}

\end{document}

When using multicol, it does not recognize allowframebreaks option in frame definition as shown in this screen shot

see the code from this question: https://tex.stackexchange.com/q/109748/36296 — samcarter_is_at_topanswers.xyz, Jun 06 '18 at 13:45
I have some 88 frames, when I used {multicols}{3}, it generated 3 columns, the first from frame 3-20, the second 25-42, the third 47-64; and the other frames are not displayed. I compiled the document 3 times. — Hany, Jun 07 '18 at 03:46
I used the multicol package with the code I posted, but I think that the problem is that the multicol package does not recognize the allowframebraks option in the frame definition. How can this be solved? — Hany, Jun 07 '18 at 07:18
You can manually insert a framebreak at the desired position, see this answer: https://tex.stackexchange.com/a/109795/36296 — samcarter_is_at_topanswers.xyz, Jun 07 '18 at 07:59
I tried your suggestion, but it does not work with my code; even after replacing {toc} with {lbf}. Also it will be very difficult to do so each time I add or remove frames. — Hany, Jun 08 '18 at 05:33
Can you include a MWE of the code you tried and which is not working? — samcarter_is_at_topanswers.xyz, Jun 08 '18 at 08:20
I appended my question with my code and a screen shot of the second page of the generated list. The first page of the list is empty. — Hany, Jun 09 '18 at 04:21

New answer

Adaptations

(in comparison to the old answer below)

removed error by using: \addtocontents{lbf}{xyz} instead of \addcontentsline{...}{xyz}{...}
problem: multicols does not work together with allowframebreaks, see:
- Beamer: allowframebreaks collides with columns?
- Allow frame breaks in multicolumn environment
work around:
- use minipage with a width of 0.49\textwidth instead of multicols
- put up to 16 entries in one minipage by using an counter lbfi
- the last minipage must be closed at the end using \lbfend in the last frame
  - note: \addtocontents can only be used together with material which is typeset (see Beamer: allowframebreaks collides with columns?)
    - I couldn't get the solution there to work with \AtEndDocument

Code

\documentclass{beamer}
\beamertemplatenavigationsymbolsempty
\usepackage{forloop}
\usepackage{multicol}
\usepackage{etoolbox}
\newif\ifframeinlbf
\frameinlbftrue
\makeatletter
\newcommand\listofframes{@starttoc{lbf}}
\makeatother
\newcounter{lbfi}
\setcounter{lbfi}{0}
\addtobeamertemplate{frametitle}{}{%
    \ifframeinlbf%
        \ifnumequal{\value{lbfi}}{16}{%
            \setcounter{lbfi}{0}
            \addtocontents{lbf}{%
                \end{minipage}
            }%
        }{}%
        \ifnumequal{\value{lbfi}}{0}{%
            \addtocontents{lbf}{%
                \begin{minipage}{.49\textwidth}%
            }%
        }{}%
        %
        \addtocontents{lbf}{%
            \protect\makebox[2em][l]{%
                \protect\usebeamercolor[fg]{structure}\insertframenumber\hfill%
            }%
            \protect\hyperlink{page.\insertpagenumber}\insertframetitle\par%
        }%
        \stepcounter{lbfi}
\else\fi%

}
\newcommand{\lbfend}{
    \addtocontents{lbf}{%
        \end{minipage}
    }%
}
\begin{document}

\forloop{ct}{1}{\value{ct} < 40}{%
    \begin{frame}{Frame \arabic{ct}}
        frame \arabic{ct}
    \end{frame}
}
\begin{frame}{last}
    \lbfend% this command must be in the last frame
\end{frame}
\end{document}

Original answer

You can use package multicol and than the multicols environment.
I used a loop to create the 20 test frames (package forloop)
I removed unused packages
(Does not work with texlive >=2022)

Code

\documentclass{beamer}
\beamertemplatenavigationsymbolsempty
\usepackage{forloop}
\usepackage{multicol}
\newif\ifframeinlbf
\frameinlbftrue
\makeatletter
\newcommand\listofframes{@starttoc{lbf}}
\makeatother
\addtobeamertemplate{frametitle}{}{%
  \ifframeinlbf
  \addcontentsline{lbf}{section}{\protect\makebox[2em][l]{%
    \protect\usebeamercolor[fg]{structure}\insertframenumber\hfill}% 
  \protect\hyperlink{page.\insertpagenumber}\insertframetitle\par}
  \else\fi
}
\begin{document}
\frameinlbffalse
\begin{frame}[fragile,t,allowframebreaks]
    \frametitle{List of Frames}
    \begin{multicols}{2} % number of columns
    \listofframes
    \end{multicols}
\end{frame}
\frameinlbftrue
\newcounter{ct}
\forloop{ct}{1}{\value{ct} < 21}%
{%
    \begin{frame}{Frame \arabic{ct}}
        frame \arabic{ct}
    \end{frame}
}
\end{document}

no need to use the forloop package. The multicol package is sufficient, but it does not recognize the allowframebreaks option in the frame definition. — Hany, Jun 07 '18 at 07:15
I tried your code but got < Runaway argument? {\protect \makebox [2em][l]{\protect \usebeamercolor [fg]{structure}\insertfram enumber \ETC. ! Paragraph ended before \addcontentsline was complete.> ---> What to do ? — Duchamp Gérard H. E., Apr 26 '23 at 05:36
@DuchampGérardH.E. I made a new answer, without that error. — dexteritas, Apr 26 '23 at 11:07
@Hany In the new answer there will be multiple frames for "List of Frames", if necessary. multicols does not work together with allowframebreaks. The forloop package is of course only for the example to create many frames automatically. — dexteritas, Apr 26 '23 at 11:09
@DuchampGérardH.E. I just tested it with overleaf: the old code works until texlive 2021 (but not 2022) and the new code works also with texlive 2022. — dexteritas, Apr 27 '23 at 15:26
@dexteritas Thank you for your concern ! I expect I must fix something in my system. — Duchamp Gérard H. E., Apr 28 '23 at 00:17
