Beamer - make itemize (and space occupied) disappear

So I have two itemize's on one slide and a graphic underneath them both:

\onslide<1>{
    \begin{itemize}
      ...
    \end{itemize}
}

\onslide<2>{
    \begin{itemize}
      ...
    \end{itemize}
}

\includegraphics[width=5cm]{abc.eps}

So what I want is for the first itemize to be visible on the first slide, and the second itemize to be invisible and not occupy any space. Similarly, when I go to the next slide, I want the first itemize to go invisible and not occupy any space while showing the second itemize. I want the graphic to be visible and stay in the same place on both sli开发者_开发问答des.

Is this possible?

Use \alt or \temporal:

\alt<n>{at n}{not at n} for two alternatives.

\temporal<n>{before}{at n}{after} for three alternatives.

One can simply combine both itemizations in a single one:

\documentclass{beamer}

\begin{document}

\begin{frame}   

\begin{itemize}
    \item<only@1> item on first slide
    \item<only@1> more item on first slide
    \item<only@2> item on second slide
    \item<only@2> more item on second slide 
\end{itemize}

\includegraphics[width=5cm]{example-image-duck}

\end{frame}

\end{document}
