[Tex/LaTex] How to have the name of all sections on the top of each page in this Beamer template

beamerpresentations

This TeX should have about 10 sections each of which has a couple of subsections under it. Also, the names of sections are all 2-words. So in this Beamer template, as you can see, the names of all sections should appear in the black stripe on the top of each page. But because the number of my sections are too many, some of them are omitted by the template. How can I fix this so that I have the name of all sections on the top of each page?

 \documentclass[
    aspectratio=169
]{beamer}

\usetheme{Darmstadt}        

\begin{document}

\section{Descriptive Outline 1}
\subsection{Outline}
\begin{frame}
\frametitle{Outline}
\end{frame}
\section{Descriptive Outline 2}
\subsection{Outline}

Squeezing an elephant into a suitcase is always difficult. One way to get a bit more space in the headline is to use another aspect ratio for the slide, e.g. 16:9.

Some other comments:

the \author{hh} in front of the documentclass does nothing, you are overwriting it in your document
you don't need \usepackage{graphicx} with beamer
please don't load the same package multiple times. Anyway the more beamerish way would be to write \usetheme{Darmstadt}

\documentclass[
    aspectratio=169
]{beamer}

\usetheme{Darmstadt}        

\begin{document}

If the sections still don't fit in the headline, then there is simply not enough space and either another theme should be used or the amount of information in the headline should be reduced.

If the font size is further decreased to accommodate all the sections, it get so small, nobody will be able to read it anyway.

 \documentclass[
    aspectratio=169

\usetheme{Darmstadt}        

\setbeamerfont{section in head/foot}{size=\fontsize{4pt}{5pt}\selectfont}

[Tex/LaTex] Customizing Beamer’s Table of Contents

For specific subsections you may modify the behavior before they start: you could change \AtBeginSubsection locally. This means you could change that, for a subsection, but keep this change local by enclosing it within a group. For example, disabling \AtBeginSubsection and thus the subsection TOC:

\begingroup
\AtBeginSubsection{}
\subsection{No TOC}
\begin{frame}
...
\end{frame}
\endgroup
\subsection{Here's a TOC}

After the group ended, the globally by \AtBeginSubsection defined macro returns being active. The following subsections will show the TOC - I tested it.

This works because \AtBeginSubsection uses \def to redefine internal macros, which works local, thus visible only inside a group, in contrary to \gdef.

[Tex/LaTex] Beamer: how to make each frame appear in the PDF toc

Here is a solution that patches an auxiliary macro in \frametitle, adding code that adds a bookmark and table-of-contents line as if it were a subsection (you can just comment this out if not wanted):

\documentclass{beamer}

\AtBeginSection{\frame{\tableofcontents[currentsection]}}

\usepackage{bookmark}
\usepackage{etoolbox}
\makeatletter
% save the current definition of \beamer@@frametitle
\let\nobookmarkbeamer@@frametitle\beamer@@frametitle
% then patch it to do the bookmarks and/or TOC entries
\apptocmd{\beamer@@frametitle}{%
  % keep this to add the frame title to the TOC at the "subsection level"
  \addtocontents{toc}{\protect\beamer@subsectionintoc{\the\c@section}{0}{#1}{\the\c@page}{\the\c@part}%
        {\the\beamer@tocsectionnumber}}%
  % keep this line to add a bookmark that shows up in the PDF TOC at the subsection level
  \bookmark[page=\the\c@page,level=3]{#1}%
  }%
  {\message{** patching of \string\beamer@@frametitle succeeded **}}%
  {\errmessage{** patching of \string\beamer@@frametitle failed **}}%

\pretocmd{\beamer@checknoslide}{%
  % ensure the bookmark is not created if the slide is filtered out
  \let\beamer@@frametitle\nobookmarkbeamer@@frametitle
  }%
  {\message{** patching of \string\beamer@checknoslide succeeded **}}%
  {\errmessage{** patching of \string\beamer@checknoslide failed **}}%

\makeatother



\begin{document}



\section{First Section}

\begin{frame}{First frame}Text\end{frame}

\begin{frame}{Second frame}Text\end{frame}



\section{Second Section}

\begin{frame}{Third frame}Text\end{frame}

\begin{frame}\frametitle{Fourth frame}Text\end{frame}

\begin{frame}<handout>\frametitle{Fifth frame}Text\end{frame}


\end{document}

I had to dig around in beamerbasesection.sty to figure that out. But it seems to work.

Output

EDIT. (by cyberSingularity): Now prevents unwanted bookmarks when the slide is not shown by also patching \beamer@checknoslide, and provided an additional frame to test.

Note: if there are frames with multiple slides (e.g. due to \pauses), you may also be interested in this follow up question.
