# beamer table of content: put only the current section and subsection at the top of the slide

I'm writing a rather long beamer, with many sections. The toc with sections fit in a single slide, but when, at each section, I show the subsections, it gets too long and we cannot see it. I would like , at each beginning of section/subsection, to display the toc for that section only, aligned at the top.

Currently, when getting to section 4, I get, where === represents the slide limit:

 ============

1. Section1
2. Section2
3. Section3
4. Section4

4.1 Subsection 41

===================

4.2 Subsection 42 (so it gets out of the slide)

5. Section5


I want to have:

==========

4. Section4 (aligned at the top of the slide !)

4.1 Subsection 41

4.2 Subsection 42

(free space here)

========


Even if i use sectionstyle=show/hide, subsectionstyle=show/shaded/hide, the position of the section is "remembered".

Thanks!

• Can you add a MWE? It would be interesting to know, which theme you are using? – user36296 Nov 16 '16 at 15:40

To only display the ToC of the current section, you can use

\documentclass{beamer}

\AtBeginSection{%
\begin{frame}
\tableofcontents[sections=\value{section}]
\end{frame}
}

\begin{document}

\section{sec1}
\subsection{sub1}
\frame{abc}

\section{sec2}
\subsection{sub2}
\frame{abc}

\end{document}
