# Beamer: Change only several bullets in the list

I would like to change the bullets in the second itemize to arrows.

\begin{alertblock}{The Aim of this Research}
\begin{itemize}
\item Item 1
\item Item 2
\begin{itemize}
\item Item 2-1
\item Item 2-2
\end{itemize}
\end{itemize}


Form above, I would like to make:

・Item 1
・Item 2
=> Item 2-1  (change bullet to arrow)
=> Item 2-2


I've tried inserting \renewcommand{\labelitemii}{$\rightarrow$} before and after the second \begin{itemize} and the solution in this question, but they don't work.

You can define your bullet symbols direct in the itemization:

\begin{itemize}
\item[$\rightarrow$] Item 1
\end{itemize}

• This can become tedious if this should be done more than once. Did you test it, by the way?

• Yes, but i think for two items it's ok. Yes, I have tested it, should i post my MWE? Feb 15 '16 at 18:22

If you wish to change the second level of all itemize lists, you can adjust the symbol associated with the itemize subitem template:

\documentclass{beamer}

\let\Tiny\tiny% http://tex.stackexchange.com/a/94159/5764

\setbeamertemplate{itemize subitem}{$\rightarrow$}

\begin{document}

\begin{frame}
\frametitle{Frame title}

\begin{alertblock}{The Aim of this Research}
\begin{itemize}
\item Item 1
\item Item 2
\begin{itemize}
\item Item 2-1
\item Item 2-2
\end{itemize}
\end{itemize}
