[Tex/LaTex] Minipage inside itemize, bullet point position

Question

Sometimes I wish to include a small diagram next to the text which I could achieve by using two mini-page, one for the text, one for the diagram. However when I use it inside itemize, the bullet point gone to the wrong place (see diagram). How can I make it so that the bullet point is in the right place (ie. next to "An")

In response to Ulrike Fischer's answer, for example the code

\documentclass{article}
\usepackage{tikz}

\begin{document}
\begin{itemize}
\item blbl

\item \begin{minipage}{4cm} some text\\some text\\some text\end{minipage}

\item \begin{minipage}[t]{4cm} some text\\some text\\some text\\some text\\some text\end{minipage}
\begin{minipage}[t]{4cm}   
  \begin{center}
    \begin{tikzpicture}
      \draw [->] (-1,-1) -- (1,-1) -- (1, 1) -- (-1, 1) -- (-1,-1);
    \end{tikzpicture}
  \end{center}
\end{minipage}

\item \begin{minipage}[t]{4cm} some text\\some text\\some text\\some text\\some text\end{minipage}
\begin{minipage}{4cm}   
  \begin{center}
    \begin{tikzpicture}
      \draw [->] (-1,-1) -- (1,-1) -- (1, 1) -- (-1, 1) -- (-1,-1);
    \end{tikzpicture}
  \end{center}
\end{minipage}

\end{itemize}
\end{document}

gives

so the tikz diagram is not next to the text.

Answer 1

Use the [t] option to align your minipage at the first line:

\documentclass{article}

\begin{document}
\begin{itemize}
\item blbl

\item \begin{minipage}{4cm} some text\\some text\\some text\end{minipage}

\item \begin{minipage}[t]{4cm} some text\\some text\\some text\end{minipage}

\end{itemize}
\end{document}

Edit

You can align the following minipage with the tikzpicture e.g. with a \vspace or by using the baseline key of tikzpicture:

\documentclass{article}
\usepackage{tikz}

\begin{document}
\begin{itemize}
\item blbl

\item \begin{minipage}{4cm} some text\\some text\\some text\end{minipage}

\item \begin{minipage}[t]{4cm} some text\\some text\\some text\\some text\\some text\end{minipage}%
\begin{minipage}[t]{4cm}
     \centering
     \begin{tikzpicture}[baseline={(1,1)}] %or some other coordinate
      \draw [->] (-1,-1) -- (1,-1) -- (1, 1) -- (-1, 1) -- (-1,-1);
    \end{tikzpicture}
\end{minipage}

\item \begin{minipage}[t]{4cm} some text\\some text\\some text\\some text\\some text\end{minipage}%
\begin{minipage}[t]{4cm}
 \centering
 \vspace{-\ht\strutbox} %or some other value.
     \begin{tikzpicture}
      \draw [->] (-1,-1) -- (1,-1) -- (1, 1) -- (-1, 1) -- (-1,-1);
    \end{tikzpicture}
\end{minipage}

\end{itemize}
\end{document}
