不同箭头中的文字

Question

也许有人可以帮助我获取下面箭头和文本框中的文字

我刚刚得到了这样的箭......

\begin{tikzpicture}
\draw[thick,black](0cm,0) -- ++(0:3cm) -- ++(45:1cm)  -- ++(135:1cm)-- ++(180:3cm)-- ++(270:1.4cm);
\draw[thick,black] (4cm,0) -- ++(0:3cm) -- ++(45:1cm)  -- ++(135:1cm)-- ++(180:3cm)-- ++(315:1cm)-- ++(225:1cm);
\draw[thick,black] (8cm,0) -- ++(0:3cm) -- ++(45:1cm)  -- ++(135:1cm)-- ++(180:3cm)-- ++(315:1cm)-- ++(225:1cm);
\end{tikzpicture}

我想要在箭头中获取文本（也许有一个节点的形状？）并将文本作为箭头下方的项目符号列表。

一种可能性是使用库signal中的形状shapes和两个链；该enumitem包用于定义带有修改后的标签的自定义列表：

\documentclass{article}
\usepackage{tikz}
\usepackage{enumitem}
\usepackage{pifont}
\usetikzlibrary{chains,shapes,shadows}

\newcommand\mycircle{%
  \tikz\draw (0,0) circle (2pt);}
\newlist{myitemize}{itemize}{2}
\setlist[myitemize]{leftmargin=*,nolistsep}
\setlist[myitemize,1]{label=\ding{227}}
\setlist[myitemize,2]{label=\mycircle}

\tikzset{
initial/.style={
  draw=blue!50!cyan!40,
  shape=signal,
  text width=3cm,
  text depth=1cm,
  top color=blue!50!cyan!10,
  bottom color=blue!50!cyan!40,
  drop shadow
  },
other/.style={
  initial,
  signal from=west,
  text width=2.26cm
},
rect/.style={
  draw=blue!50!cyan!40,
  rectangle,
  text width=3cm,
  text depth=7cm,
  text height=5pt,
  top color=blue!50!cyan!10,
  bottom color=blue!50!cyan!40,
  drop shadow
  }
}

\begin{document}

\begin{tikzpicture}
\begin{scope}[start chain,node distance=5mm, every node/.style={on chain}]
\node[initial] {text 1};
\node[other] {text 2};
\node[other] {text 3};
\end{scope}
\begin{scope}[yshift=-4.8cm,start chain,node distance=5mm, every node/.style={on chain}]
\node[rect] {%
  \begin{myitemize}
  \item First.
  \item Second.
    \begin{myitemize}
    \item First.
    \item Second.
  \end{myitemize}
  \end{myitemize}%
};
\node[rect] {%
  \begin{myitemize}
  \item First.
  \item Second.
  \end{myitemize}%
};
\node[rect] {%
  \begin{myitemize}
  \item First.
  \item Second.
  \item Third.
  \end{myitemize}%
};
\end{scope}
\end{tikzpicture}

\end{document}
