# On inverting navigation bar and footer contents

I'm using the Frankfurt theme in beamer. It includes a sort of navigation bar with (sub-)section titles and a circle per slide in each (sub-)section. I'd like to move such a bar to the bottom of the page and displaying the footer at the header place.

Do you know what should I do?

Edit:

1) How can I avoid to display that footer in the title slide?

2) How can I display the title of the presentation and the name of the author, say as in  Berlin theme? I tried to use the suggested preamble using Berlin but it does not work.

• I removed the thanks. It may seem a little odd, but this is just the style of TeX.sx. Thanks is best expressed by up voting answers as people try to help you. – qubyte Nov 21 '11 at 15:11
• Frankfurt alone doesn't produce any footer, since it uses the smoothbars outer theme which sets the headline template but doesn't set the footline template. How are you producing the footer? – Gonzalo Medina Nov 21 '11 at 16:32

Frankfurt uses the smoothbars outer theme which sets the headline template but doesn't set the footline template. To change the header position to the bottom of the frame, it's enough to set the footline template to behave exactly as smoothbars sets the headline template. To place the navigation symbols in the header, you need to redefine the navigation symbols template to do nothing and then to insert the symbols in the headline template:

\documentclass{beamer}
\usetheme{Frankfurt}

\makeatletter
\setbeamertemplate{footline}
{%
\ifbeamer@sb@subsection%
\vskip-9.75ex%
\else%
\vskip-7ex%
\fi%
\end{beamercolorbox}%
\ifbeamer@sb@subsection%
\begin{beamercolorbox}[ignorebg,ht=2.125ex,dp=1.125ex,%
\end{beamercolorbox}%
\fi%
}%
