I'm trying to create a custom beamer template. However, I can't make the navigation bar to correctly behave in the title page.
As shown in the image, where the navigation bar is supposed to be I get a white bar instead of the navigation bar. How can I make it totally invisible, so the background fill the entire frame? And while maintaining the navigation bar on the other slides.
As you can see, I tried several things:
- To rewrite the
\titlepagecommand to automatically redefine theheadlinepart, but it didn't work. BONUS: I would really like a solution on these lines, as it allows me to also removefootlines, or other tweaks that need to be removed from thetitle page. However, I can't control the expansion of the declared macros. - To manually reset
headlinebefore calling it in the example. However, I would prefer an automatic solution. - To add a condition (
\ifnum\thepage>1\relax) on the headline to behave differently for the first page, but it removes the navigation bar from the first slide too. This was the closest to a solution I got.
The code is:
\documentclass[compress]{beamer}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{tikz}
