I am inserting the list of section names in the footer using:
```
\vskip2pt\insertnavigation{\paperwidth}\vskip-2pt
```
The complete code for the footer (using the metropolis theme) is
```
\makeatletter
\setbeamertemplate{footline}{%
\begin{beamercolorbox}[wd=\textwidth, sep=3ex]{footline}%
\usebeamerfont{page number in head/foot}%
\usebeamertemplate*{frame footer}
\hfill%
\usebeamertemplate*{frame numbering}
\end{beamercolorbox}%
\begin{beamercolorbox}[colsep=1.5pt]{upper separation line head}
\end{beamercolorbox}
\begin{beamercolorbox}{section in head/foot}
\vskip2pt\insertnavigation{\paperwidth}\vskip-2pt
\end{beamercolorbox}%
\begin{beamercolorbox}[colsep=1.5pt]{lower separation line head}
\end{beamercolorbox}
}
\makeatother
```
However I have too many sections and it escapes the end of the footer. See picture of slide:
[![enter image description here][1]][1]
To fix this I would like to move the navigation to the left as the current section increases. Something like:
```
\vskip-{\sectionnumber}pt\insertnavigation{\paperwidth}\vskip-2pt
```
where `\sectionnumber` is the number of the current section (made up the command).

The problem with moving the content by a fixed amount of space for each section is that this does not take into acocunt different lenghts of section names.
However using a similar approach as in https://topanswers.xyz/tex?q=415#a418 you can show only a fixed number of sections in the navigation bar, e.g. the current section +-2 other sections.
```

\usebeamertemplate*{frame numbering}

\begin{beamercolorbox}[colsep=1.5pt]{upper separation line head}

\begin{beamercolorbox}{section in head/foot}
\vskip2pt\insertnavigation{\paperwidth}\vskip2pt
