# zoom in with enumerated list in beamer

I would like to create an enumerated list, with some more details on a second slide. What I try is the following

Slide A

1 First
2 Second
3 Third


However, on slide B I would like to display

1 First
2 Another topic before Second
3 Yet another topic before Second
4 Second
5 Third


It should be displayed, that item number 2 on slide A is the same than topic number 4 on slide B. It would be nice to get fancy replys.

This works:

\documentclass{beamer}
\begin{document}
\begin{frame}
\begin{enumerate}
\item First
\only<2->{
\item Another topic before Second
\item Yet another topic before Second}
\item Second
\item Third
\end{enumerate}
\end{frame}
\end{document}


But I recommend this instead, agreeing with AlexG:

\documentclass{beamer}
\begin{document}
\begin{frame}
\begin{enumerate}
\item First
\item<2-> Another topic before Second
\item<2-> Yet another topic before Second
\item Second
\item Third
\end{enumerate}
\end{frame}
\end{document}
