I want to modify miniframes theme in order to not display the bullets, but to show in the lower bar the titles of all the subsections of the current section. I did it modifying miniframe theme file: I eliminated \insertnavigation
in the colorbox corresponding to sections and I inserted \insertsubsectionnavigationhorizontal
in the colorbox corresponding to subsections as follows:
\begin{beamercolorbox}[center, ht=2.5ex,dp=1.125ex, leftskip=.3cm,rightskip=.3cm plus1fil]{subsection in head/foot}
\usebeamerfont{subsection in head/foot}
\insertsubsectionnavigationhorizontal {\textwidth}{\hfill}{\hfill}
\end{beamercolorbox}%
It works correctly just if I have one section with subsections, while it is not able to recognize all the subsections if there are more than one sections with subsections. What should I do to display correctly the subsections titles? I don't know if I was clear enough, but I hope you can help me!
