I have a lot of sections in my beamer presentation. Because of that I cannot see all of them in the header.
Since I'm using the Darmstadt theme, it seems that the header has enough space two write the sections in 2 lines.
How can I do that? I could use other theme too.
\documentclass[hyperref={pdfpagelabels=false},xcolor=dvipsnames]{beamer}
\usepackage{lmodern}
\usepackage[utf8]{inputenc}
\usepackage{subfigure}
\usepackage{wasysym}
\usepackage{pdfpages}
\usepackage{beamerthemeshadow}
\usepackage{caption}
\usepackage{xcolor}
\usepackage{multicol}
\usetheme{Darmstadt}
\begin{document}
\begin{frame}
\titlepage
\end{frame}
\begin{frame}\frametitle{TOC}
\begin{multicols}{2}
\tableofcontents
\end{multicols}
\end{frame}
\section{Section 1}
\begin{frame} \frametitle{Section 1}
\end{frame}
\end{document}
Thanks
