enumitem: multiline label with text following label

Question

How can I make a multi-line description label with the description following the label instead of under the label, on a new line?

I currently use:

\usepackage{enumitem}
:
\setlist[description]{leftmargin=0em}
:
\begin{description}
  \item [{\parbox[t]{1\linewidth}{Optimization of molecular methods and
  statistical procedures for forensic fingerprinting of microbial
  soil communities}}]
  description of this item
\end{description}

Which gives me multiline but (of course) the text comes on a new line underneath the label.

Desired result is:

Optimization of molecular methods and statistical procedures for forensic fingerprinting of microbial soil communities description of this item

Answer 1

As @Christoph Frings says, this partly what style=sameline does. You are also working too hard in that you do not need to put the label into a \parbox, as the enumitem package will take care of this for you. In fact, using the \parbox forces the line break that you don't want!

With these two changes your MWE produces:

Here is the full code:

\documentclass{article}
\usepackage{enumitem}
\begin{document}

\setlist[description]{leftmargin=0em,style=sameline}
\begin{description}
  \item [Optimization of molecular methods and statistical procedures
  for forensic fingerprinting of microbial soil communities]
  description of this item
\end{description}
\end{document}
