itemize, removing natural indent

Question

When you itemize items you usually have the entire list indented. This is expected when you have a title or description of what you are listing. I want to itemize but not have the natural indent. I need to move all of the bullet points over towards the the leftmost edge of the margin like all other text you would enter. How can I do this?

Answer 1

Any customization of a list environment, such as itemize, enumerate, etc, is most elegantly handled by the enumitem package.

You can use leftmargin=* locally,

\begin{itemize}[leftmargin=*]
  \item one 
  \item two
  \item three
\end{itemize}

or else you use

\setlist[itemize]{leftmargin=*}

in your preamble to make the change global.

\documentclass{article}
\usepackage[showframe=true]{geometry}
\usepackage{enumitem}

\begin{document}

\begin{itemize}
  \item one 
  \item two
  \item three
\end{itemize}

\begin{itemize}[leftmargin=*]
  \item one 
  \item two
  \item three
\end{itemize}
\end{document}

Answer 2

emumitem package is a convenient tool. Since version 3.6, it offers a key called "left", with which one can set two tabstops one for the start of label and another for the start of the text. For example in the following MWE:

\documentclass{article}
\usepackage{enumitem}
\setlist[itemize]{align=parleft,left=0pt..1em}
%
\begin{document}
%
\begin{itemize}
\item first item
\item second item
\end{itemize}
%
\end{document}

align=parleft aligns the label to left in the parbox of size \labelwidth. left=0pt..1em means that the label (bullet symbol) begins at the margin, and the subsequent text (first item, second item etc.) start at 1em from the margin.
