我在环境中有一部分投影仪框架\columns。当\item左列出现时，右列的树形图会上下跳动。我想让图表在幻灯片之间保持在同一位置。
我有整个框架，\overlayarea但这似乎没有帮助。
这是我的妈妈：
\documentclass[12pt]{beamer}
\usepackage[utf8]{inputenc}
\usepackage[ngerman]{babel}
\usepackage[linguistics]{forest}
\begin{document}
\begin{frame} \footnotesize
\frametitle{A Heading for my Frame}
\begin{itemize}
\item This is an item.
\end{itemize}
\begin{overlayarea}{\textwidth}{.9\textheight}
\begin{itemize}
\item Some more Items
% \onslide*<2-7>{
\begin{itemize}
\item<2-> This is an item
\item<5-> This is an item
\end{itemize}%}
\item<8-> More Items
\end{itemize}
\begin{columns}
\begin{column}{.15\textwidth}
\onslide+<9->{
% \scalebox{.8}{
\begin{tikzpicture}
\node[draw](tree){
\begin{forest}
[ VP
[ VP
[ Node ]
[ Node]]
[ Node ]]
\end{forest}};
\onslide+<12->{
\draw[red, thick] (tree.south east) to (tree.north west);
\draw[red, thick] (tree.south west) to (tree.north east);}
\end{tikzpicture}}%}
\end{column}
\begin{column}{.6\textwidth}
\begin{itemize}
\item<10-> This is a relatively long question that stretches two lines ?
\onslide*<11-12>{
\begin{itemize}
\item
\begin{itemize}
\item *Here the whole thing jumps
\item *Here the whole thing jumps
\item *Here the whole thing jumps
\end{itemize}
\end{itemize}}
\item<13-> Everything jumps back.
\item<14-> Concluding remarks.
\end{itemize}
\end{column}
\end{columns}
\end{overlayarea}
\end{frame}
\end{document}

后面留空一行即可This is a relatively long question that stretches two lines ?
