Hide subitem in Beamer

beamer add tag

**My question**

How to hide `subitem` in a `list` in `beamer`?

**Context**


I like to keep my slides with minimal text and maximum graphs.

Lists are boring on presentations. I'd like to display only the main ideas (`level 1` of my `list`) and display the complete `list` in `article` mode.

**MWE**

```
\documentclass{beamer}

%\documentclass{article}
%\usepackage{xcolor}
%\usepackage{beamerarticle}
%\usepackage{enumitem}

\newcommand{\boldflatitem}{%
	\mode<article>{
		\setlist[enumerate,1]{%
			label = \textcolor{red}{\arabic*.},
			font  = \bfseries,
			before = \bfseries
		}
		\setlist[itemize,1]{%
			font = \normalfont,
			before = \normalfont,
		}
	}
		
	\mode<beamer>{
		\setbeamerfont{itemize/enumerate body}{series=\bfseries}
        %\setbeamertemplate{itemize/enumerate subbody}{}
		\setbeamerfont{itemize/enumerate subbody}{series=\normalfont}
	}
			
}

\begin{document}

\begin{frame}
		\boldflatitem{}	
		\begin{enumerate}
			\item level 1
			      \begin{itemize}
			      	\item level 2
			      	\item level 2
			      \end{itemize}	
			\item level 1
			      \begin{itemize}
			      	\item level 2
			      	\item level 2
			      \end{itemize}		      			      		
		\end{enumerate}
\end{frame}    

\end{document}
```

You can hide the itemize environments from beamer mode with `\begin{itemize}[<beamer:only@0>]`.

off-topic: 

- just to be on the safe side and not accidentally load `enumitem` with beamer: warp it in `\mode<article>{\usepackage{enumitem}}`

- you don't need to load `xcolor`. Unless you use the `noxcolor` option, beamerarticle will load the package automatically

```
%\documentclass{beamer}

\documentclass{article}
\usepackage{beamerarticle}
\mode<article>{\usepackage{enumitem}}

\newcommand{\boldflatitem}{%
	\mode<article>{
		\setlist[enumerate,1]{%
			label = \textcolor{red}{\arabic*.},
			font  = \bfseries,
			before = \bfseries
		}
		\setlist[itemize,1]{%
			font = \normalfont,
			before = \normalfont,
		}
	}
		
	\mode<beamer>{
		\setbeamerfont{itemize/enumerate body}{series=\bfseries}
        %\setbeamertemplate{itemize/enumerate subbody}{}
		\setbeamerfont{itemize/enumerate subbody}{series=\normalfont}
	}
			
}

\begin{document}

\begin{frame}
		\boldflatitem{}	
		\begin{enumerate}
			\item level 1
          \begin{itemize}[<beamer:only@0>]
              	\item level 2
              	\item level 2
          \end{itemize}	
			\item level 1
          \begin{itemize}[<beamer:only@0>]
              	\item level 2
              	\item level 2
          \end{itemize}	
		\end{enumerate}
\end{frame}    

\end{document}
```

Cause I get an error otherwise :) "runaway argument" ``` %\documentclass{beamer} \documentclass{article} \usepackage{beamerarticle} \mode<article>{\usepackage{enumitem}} %\mode<article>{ %\newenvironment{hideBitem}[1][]{\begin{itemize}[#1]}{\end{itemize}} %} %\mode<beamer>{ \newenvironment{hideBitem}[1][]{ \begin{itemize}[<beamer:only@0>,#1]}{% \end{itemize} } %} \newcommand{\boldflatitem}{% \mode<article>{ \setlist[enumerate,1]{% label = \textcolor{red}{\arabic*.}, font = \bfseries, before = \bfseries } \setlist[itemize,1]{% font = \normalfont, before = \normalfont, } } \mode<beamer>{ \setbeamerfont{itemize/enumerate body}{series=\bfseries} \setbeamerfont{itemize/enumerate subbody}{series=\normalfont} } } \begin{document} \begin{frame}{Initial enumerate/itemize} \boldflatitem{} \begin{enumerate} \item level 1 \begin{itemize} \item level 2 \begin{enumerate} \item level 3 \item level 3 \end{enumerate} \item level 2 \end{itemize} \item level 1 \begin{itemize} \item level 2 \item level 2 \end{itemize} \end{enumerate} \end{frame} \begin{frame}{Boldflatitem + enumerate/hideBitem} \boldflatitem{} \begin{enumerate} \item level 1 \begin{hideBitem} \item level 2 \begin{enumerate} \item level 3 \item level 3 \end{enumerate} \item level 2 \end{hideBitem} \item level 1 \begin{hideBitem} \item level 2 \item level 2 \end{hideBitem} \end{enumerate} \end{frame} \begin{frame}{Boldflatitem + beamer:only } \boldflatitem{} \begin{enumerate} \item level 1 \begin{itemize}[<beamer:only@0>] \item level 2 \begin{enumerate} \item level 3 \item level 3 \end{enumerate} \item level 2 \end{itemize} \item level 1 \begin{itemize}[<beamer:only@0>] \item level 2 \item level 2 \end{itemize} \end{enumerate} \end{frame} \end{document} ```

why do you need the different definitions for article and beamer mode? The whole point of `<beamer:only@0>` is that it will hide the environment in beamer mode and display it in article mode. The `<beamer:only@0>` won't hurt in article mode

If I'm not wrong, it should look like this : ``` \documentclass{beamer} %\documentclass{article} %\usepackage{beamerarticle} \mode<article>{\usepackage{enumitem}} \mode<article>{ \newenvironment{jetitem}[1][]{\begin{itemize}[#1]}{\end{itemize}} } \mode<beamer>{ \newenvironment{jetitem}[1][]{\begin{itemize}[<beamer:only@0>,#1]}{\end{itemize} } } \newcommand{\boldflatitem}{% \mode<article>{ \setlist[enumerate,1]{% label = \textcolor{red}{\arabic*.}, font = \bfseries, before = \bfseries } \setlist[itemize,1]{% font = \normalfont, before = \normalfont, } } \mode<beamer>{ \setbeamerfont{itemize/enumerate body}{series=\bfseries} \setbeamerfont{itemize/enumerate subbody}{series=\normalfont} } } \begin{document} \begin{frame}{Initial enumerate/itemize} \boldflatitem{} \begin{enumerate} \item level 1 \begin{itemize} \item level 2 \begin{enumerate} \item level 3 \item level 3 \end{enumerate} \item level 2 \end{itemize} \item level 1 \begin{itemize} \item level 2 \item level 2 \end{itemize} \end{enumerate} \end{frame} \begin{frame}{boldflatitem + enumerate/jetitem} \boldflatitem{} \begin{enumerate} \item level 1 \begin{jetitem} \item level 2 \begin{enumerate} \item level 3 \item level 3 \end{enumerate} \item level 2 \end{jetitem} \item level 1 \begin{jetitem} \item level 2 \item level 2 \end{jetitem} \end{enumerate} \end{frame} \begin{frame}{boldflatitem + beamer:only } \boldflatitem{} \begin{enumerate} \item level 1 \begin{itemize}[<beamer:only@0>] \item level 2 \begin{enumerate} \item level 3 \item level 3 \end{enumerate} \item level 2 \end{itemize} \item level 1 \begin{itemize}[<beamer:only@0>] \item level 2 \item level 2 \end{itemize} \end{enumerate} \end{frame} \end{document} ```

That's what I need indeed !! :) I added this `\boldflatitem` command this emphasize list that are `enumerate`d then `item`ized. But an environment might be better indeed. How ould you build it then ?
