{beamer} TOC like standard paragraph

Question

The TOC in LaTeX seams to be an itemize environment.

Is it possible to change that in {beamer}, so that the TOC renders like an standard paragraph including line beaks if it gets longer than \linewidth?

My desired output should look like this:

\documentclass[14pt]{beamer}
\begin{document}
\section{Section1}
\section{Section2}
\section{Section3}
\section{Section4}
\section{Section5}
\section{Section6}
\section{Section7}
\frame{{TOC}
    \tableofcontents
}
\end{document}

Answer 1

I did not find the exact solution, but the second best was the use of the {multicol} package. The solution is to combine multiple {multicol} parts along wit the restriction of \tableofcontents to certain sections:

\documentclass[14pt]{beamer}
\usepackage{multicol}
\begin{document}
\section{Section1}
\section{Section2}
\section{Section3}
\section{Section4}
\section{Section5}
\section{Section6}
\section{Section7}

\frame{{TOC}
%% first TOC row
            \begin{multicols}{4}  
                \vspace*{-.5em} % first column has a vertical "indent" I could not come around otherwise

                \tableofcontents[sections=1-4]  
            \end{multicols}

%% second TOC row
            \begin{multicols}{4}  
                \vspace*{-.5em} % first column has a vertical "indent" I could not come around otherwise

                \tableofcontents[sections=5-8]  
            \end{multicols}

%% third TOC row
            \begin{multicols}{4}  
                \vspace*{-.5em} % first column has a vertical "indent" I could not come around otherwise

                \tableofcontents[sections=9-12]  
            \end{multicols}

}

\end{document}

Result:
