[Tex/LaTex] Adding section indicator to Metropolis theme

beamerbeamer-metropolisthemes

I really like the Metropolis colour theme and is planning to tweak around it to make it 'mine'-ish. One thing that my supervisor is quick picky about is having some section navigation in a presentation. The good examples I can find are here and another one.

Any suggestions on how I could achieve that while keeping the colour theme? (I don't even know the correct jargon for those lines, so I tried googling terms like 'section header/section navigator footer/ etc' but it was not off good help.

The first example you linked to, uses a modified version of the Berlin theme, which in return uses the headline from the miniframe theme. You can simply keep using the metropolis theme and add this headline.

What is left for you to do, is to decide which colours you want to have - just modify \setbeamercolor{section in head/foot}{fg=normal text.bg, bg=structure.fg}

\documentclass{beamer}

\usetheme{metropolis}

\makeatletter
\setbeamertemplate{headline}{%
  \begin{beamercolorbox}[colsep=1.5pt]{upper separation line head}
  \end{beamercolorbox}
  \begin{beamercolorbox}{section in head/foot}
    \vskip2pt\insertnavigation{\paperwidth}\vskip2pt
  \end{beamercolorbox}%
  \begin{beamercolorbox}[colsep=1.5pt]{lower separation line head}
  \end{beamercolorbox}
}
\makeatother

\setbeamercolor{section in head/foot}{fg=normal text.bg, bg=structure.fg}

\begin{document}

\section{section 1}
\subsection{section name}
\begin{frame}
\frametitle{blub}
    abc
\end{frame} 
\begin{frame}
\frametitle{blub}
    abc
\end{frame} 

\section{section 2}
\begin{frame}
\frametitle{blub}
    abc
\end{frame} 

\section{section 3}
\begin{frame}
\frametitle{blub}
    abc
\end{frame}     

\end{document}

[In case you prefer the navigation bar from the second template you linked to, you can have a look into beamerouterthemesplit.sty and take the headline from there - but personally I don't think this will look good with metropolis, as the dark frametitle is already a quite dominant element and does not need the large headline from the split theme.]
