mdframed and a title with a footnote

Question

I have put the title of my text in mdframed, however the title has a footnote. After I LaTeX the file, the footnote appears inside the frame rather than in its usual place, i.e. at the bottom of the page. I wonder how this problem can be fixed.

Answer 1

Using a separate \footnotemark-\footnotetext combination should work, as in the following minimal working example. The former inside and the latter outside the mdframed environment:

\documentclass{article} 
\usepackage{mdframed}% http://ctan.org/pkg/mdframed
\usepackage[paperheight=15\baselineskip]{geometry}% http://ctan.org/pkg/geometry
\begin{document}
\begin{mdframed}
  Some text\footnote{A footnote}.
\end{mdframed}
\bigskip
\begin{mdframed}
  Some text\footnotemark.
\end{mdframed}
\footnotetext{Another footnote.}
\end{document}

geometry was used just for this example.

For page-breaking related placement of footnotes, the following is a possibility, however hackish. Using the above approach, \footnotetext will only place the footnote at the end of the mdframed, possibly on an incorrect page. Manual adjustment of the footnote counter could help:

\documentclass{article} 
\usepackage{lipsum,mdframed}% http://ctan.org/pkg/{lipsum,mdframed}
\usepackage[paperheight=15\baselineskip]{geometry}% http://ctan.org/pkg/geometry
\begin{document}
\begin{mdframed}
  Some text\footnote{A footnote}.
\end{mdframed}
\bigskip
\stepcounter{footnote}
\footnotetext{Another footnote.}
\addtocounter{footnote}{-1}
\begin{mdframed}
  Some text\footnotemark. \par
  \lipsum[1]
\end{mdframed}
\end{document}

Using \footnotetext[\the\numexpr\value{footnote}+1\relax]{Another footnote.} could also work, assuming an \arabic setting for a footnote.
