# Beamer navigation bullets without text

How can I show navigation bullets without text above? In the following example:

\documentclass[ngerman]{beamer}
\usetheme{Frankfurt}
\usecolortheme{beaver}
\useinnertheme{rounded}
\begin{document}
\section{Sec 1}
\subsection{Sec 1}
\begin{frame}
1
\end{frame}
\section{no text}
\subsection{no text}
\begin{frame}
2
\end{frame}
\end{document}


I want no text above the second dot.

• but you want the dot, right? I have a solution, but do you need the tableofcontents in the document? – Moriambar May 20 '17 at 12:10
• @Moriambar The same as me? – TeXnician May 20 '17 at 12:14
• @TeXnician I used [\space] – Moriambar May 20 '17 at 12:18

\section[~]{no text}
