How to get rid of navigation bars in beamer?

How can I remove the navigation bar of sections and subsections on the top of each slide generate开发者_Python百科d from a beamer latex file?

I'm using the package beamerthemesplit.

The easiest way to remove the section navigation at the top of the frame is to change the headline template.

\documentclass{beamer}

\useoutertheme{split}
\setbeamertemplate{headline}{}

\begin{document}

\section{title}
\begin{frame}
\end{frame}

\end{document}

Beamer has different themes you can use, some of which include that navigation bar and some of which don't. The default theme, for example, doesn't include any navigation bar. All the themes available with Beamer are described in the user guide; just pick one that suits your requirements and use it:

\usetheme{default}

for example.

If you want to alter an existing theme to remove the navigation bar, you can try setting

\useoutertheme{default}

and see if that gives you a look you like. If not, you'll probably have to get into some theme-specific manipulations. The information needed to do this is in the user guide I linked to above.

The stupid way to make sure the presentation structure does not show up, (independent of theme) comment out the \section and \subsection commands.
