Beamer: combining footnote in one column with figure in the other one

Question

I'd like to put a figure next to a list which contains a footnote. Without the footnote everything works fine. But when I add the footnote, the figure gets shifted to the right and partly appears to be outside the frame margin. I'd like to put the figure back to where it was before I added the footnote. Here is an MWE:

\documentclass{beamer}

\begin{document}

\frame{\frametitle{Title}

\begin{columns}[c]

    \begin{column}[r]{5cm}
        \begin{itemize}[<+->]
        \item The first item
        \item The second item\footnote{A footnote}
        \item The third item
        \end{itemize} 
    \end{column}

    \begin{column}[l]{5cm}
        {\rule{2cm}{2cm}}%
        %\includegraphics
    \end{column}

\end{columns}   

}

\end{document}

Any idea how to solve this problem?

Answer 1

You can use a minipage:

\documentclass{beamer}

\begin{document}

\begin{frame}
\frametitle{Title}
\begin{columns}[c]

    \begin{column}[l]{5cm}
    \begin{minipage}[t]{5cm}
        \begin{itemize}[<+->]
        \item The first item
        \item The second item\footnote{A footnote}
        \item The third item
        \end{itemize}
    \end{minipage} 
    \end{column}

    \begin{column}[l]{5cm}
        \rule{2cm}{2cm}%
        %\includegraphics
    \end{column}

\end{columns}   
\end{frame}

\end{document}
