[Tex/LaTex] Tree like items list

Question

I'm trying to build a list in a file based on the Tufte-Latex book template: https://code.google.com/p/tufte-latex/

In keeping with the clean design, I don't need any font changes, blod or italics, and would prefer to avoid bullet points. Any idea how I can recreate the neat line-marking of this example?

Answer 1

Quick hack with Tikz, I'm sure this can be improved/made more general with some work:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shadows}

\newcommand{\mylist}{\tikz[overlay]\draw(-.2,-.2)--(-.2,.5) [path fading=east](-.2,.15)--(.1,.15);}
\newcommand{\myitem}{\item[\mylist]}
\begin{document}
\begin{enumerate}
   \item Google
   \begin{itemize}
      \myitem Picasa
      \myitem Feedburner
      \myitem Youtube
   \end{itemize}
   \item Microsoft
   \begin{itemize}
      \myitem Corel Corporation
      \myitem Zignlas
      \myitem MyBlogLog
   \end{itemize}
\end{enumerate}
\end{document}
