Setting itemindent in enumerate environment

Question

\documentclass{report}
\usepackage{amsmath}
\usepackage{enumitem}
\usepackage{lipsum}

\begin{document}

I want to make this numbered list : 

\begin{enumerate}
[leftmargin=*, labelindent=15pt, labelsep=1.0em, font=\normalfont, label=\arabic*)]
  \item \lipsum[1]
  \item \lipsum[2]
\end{enumerate}

Look like this : 

1)\quad \lipsum[1]

2)\quad \lipsum[2]

\end{document}

Answer 1

You could use the wide option as shown in the following MWE:

\documentclass{report}
\usepackage{enumitem}
\usepackage{lipsum}

\begin{document}
\begin{enumerate}
[labelsep=1.0em, font=\normalfont, label=\arabic*), wide=\parindent]
  \item \lipsum[1]
  \item \lipsum[2]
\end{enumerate}
\end{document}

With this convenience key, the leftmargin is null and the label is part of the text—in other word, the items look like ordinary paragraphs.[...]

See section '3.9 “Wide” lists' of the enumitem documentation for more details.

To indent the first line of the items equally to the indentation of paragraphs, you can use wide=\parindent or just wide.
