I'm using the BAposter class to prepare a poster and I would like to have one of the boxes without title.

If I leave the title parameter blank:

\headerbox{}{name=myBox,...}{myText}


Then it still displays the header of the box.

Any ideas on how to hide the header of the box? Thanks

• Welcome to TeX.SX! Please help us (and also you) and add a minimal working example (MWE), that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass and ending with \end{document}. Jul 11 '18 at 9:21
• If I'm not wrong, baposter boxes always declare a title part. You could leave it empty and use the background color of text part, but the space is always there. If you need nontitled boxes and you are starting with your poster a good alternative could be tcbposter (from tcolorbox package), it uses a boxes placement system similar to baposter and you can use nontitled boxes. Some examples: tex.stackexchange.com/a/378438/1952, tex.stackexchange.com/a/387491/1952 and a tutorial. Jul 11 '18 at 9:31
• With tcbposter you'll have to manually select font size. It doesn't scale automatically like baposter does. Jul 11 '18 at 9:33

The height of the posterbox header is given by the boxheaderheight key. If no posterbox header is required, set the boxheaderheight to 0em as one of the keys passed to the posterbox environment.

More generally, all the keys available in the poster environment are available to the posterbox environment. This permits extensive customization of individual posterboxes. This is illustrated by changing the posterbox header colour (headerColorOne) from blue to green and the font color for the header from white to black for the fourth posterbox.

The MWE:

\documentclass[landscape,a0paper]{baposter}

\begin{document}

\begin{poster}{
grid=false,
columns=2,
colspacing=4.2mm,
background=none,
eyecatcher=false,
%posterbox options
borderColor=red,
textborder=rectangle,
boxColorOne=white,
textfont=\normalsize\sffamily,
linewidth=1pt
}
{}
{Title}
{\textsc{Author}}
{}

\begin{posterbox}[name=box1,column=0,column=0,row=0,span=1]{Title}
This box has a header. The height of the box header is given by the key \texttt{boxheaderheight}.
\end{posterbox}

where \texttt{height} is some height measure like 4em. Add the key to the options passed
to the \texttt{posterbox} environment.
\end{posterbox}

\end{posterbox}
