[texhax] How to prevent page break in description environment item

[Moritz Sichert]

Thanks for your help!

I ended up defining my own environment like this:

\makeatletter
\let\orig at item\@item
\newcommand{\@labelparsitem}[2]{
    \parbox{\linewidth}{
       \orig at item[#1] \hspace{\linewidth} \\
       #2 \vspace{\parsep}
    }
}

\newenvironment{labelpars}{
    \let\item\@labelparsitem
    \list{}{
        \labelwidth\z@ \itemindent-\leftmargin
        \let\makelabel\descriptionlabel
    }
}{\endlist\vspace{\partopsep}}
\makeatother


that I can use like this:

\begin{labelpars}
    \item{First Item}{Description of first item}
    \item{Second Item}{Description of Second item}
\end{labelpars}
