Remove indentation on description list

Question

Ok, I looked at some answers, and they suggest to use the package enumitem and the option [leftmargin=*].

\documentclass{article}
\usepackage{enumitem}

\begin{document}
  \section{Foo}
    \subsection{Bar}
      \subsection{Foobar}
        \paragraph{Fubar}
          \begin{description}[leftmargin=*]
            \item[First Item] The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog.
            \item[Second Item] The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog.
          \end{description}
\end{document}

But this does not completely remove the indentation. Here's the result (notice the space before "fox").

On the other hand, leftmargin=0cm works, but I'm afraid it's not the same thing.

If the whole list is indented, I want the wrapped text to indent under at the start of the label, not at the left margin of the page.

I'm using a fresh installation of the latest MikTex (21 Oct 2014) x64, together with the latest TexStudio (2.8.6) on Windows 7 SP1 x64.

Answer 1

Use \leftmargin=0pt to shift the indentation to the left boundary, this works in multiply nested lists.

\documentclass{article}
\usepackage{enumitem}

\begin{document}
  \section{Foo}
    \subsection{Bar}
      \subsection{Foobar}
        \paragraph{Fubar}
        \begin{itemize}
          \item
          \begin{description}[leftmargin=0pt]
            \item[First Item] The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog.
            \item[Second Item] The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog.
          \end{description}
          \end{itemize}
\end{document}

You can also use [wide=0\parindent]:

\documentclass{article}
\usepackage{enumitem}

\begin{document}
  \section{Foo}
    \subsection{Bar}
      \subsection{Foobar}
        \paragraph{Fubar}
          \begin{description}[wide=0\parindent]
            \item[First Item] The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog.
            \item[Second Item] The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog.
          \end{description}
\end{document}
