Is it possible to create a list with lines connecting elements in the same level?

Question

I'm trying to replicate the following in LaTex:

Is there a package that can do it, or a simple way to do it? I've searched around, but couldn't find anything the made exactly this (probably due to wrong keywords).

Thanks in advance.

Answer 1

dirtree is a package specifically designed for these kinds of diagrams. However, I'd probably use Forest's edge library's (misleadingly named) folder style.

\documentclass[border=10pt,multi,tikz]{standalone}
\usepackage[edges]{forest}
\begin{document}
\begin{forest}
  for tree={
    folder,
    grow'=0,
    align=left,
    % Sašo: http://chat.stackexchange.com/transcript/message/35178162#35178162
    child anchor=mid west,
  },
  [Things it is time to speak of \dots
    [Shoes
      [An invention designed to mitigate the\\disadvantages suffered by the wealthy as a\\result of inflicting roads on the poor.]
    ]
    [Ships
      [Occasionally to be found in bottles.]
    ]
    [Sealing was
      [Not to be confused with ceiling wax.]
    ]
    [Cabbages
      [{Plant of historical importance for its role\\in the production of a soup, ostensibly\\given from charity, but actually inflicted\\as punishment for misfortune.}]
    ]
    [Kings
      [Hereditary obsolescence.]
    ]
    [Why the sea is boiling hot
      [\emph{Non sequitur}.]
    ]
    [Whether pigs have wings
      [Falsehood.
        [\emph{A posteriori.}]
        [Contingent.]
      ]
    ]
  ]
\end{forest}
\end{document}

Answer 2

This works: (minor adaptation of texample)

\documentclass{minimal}
\usepackage{tikz}
%%%<
\usepackage{verbatim}
\usepackage[active,tightpage]{preview}
\PreviewEnvironment{tikzpicture}
\setlength\PreviewBorder{5pt}%
%%%>
