itemize
\begin{itemize} \item item1 \item item2 ... \end{itemize}
The itemize
environment produces an “unordered”, “bulleted”
list. Itemizations can be nested within one another, up to four
levels deep. They can also be nested within other paragraph-making
environments, such as enumerate
(see enumerate).
Each item of an itemize
list begins with an \item
command.
There must be at least one \item
command within the environment.
By default, the marks at each level look like this:
The itemize
environment uses the commands \labelitemi
through \labelitemiv
to produce the default label. So, you can
use \renewcommand
to change the labels. For instance, to have
the first level use diamonds:
\renewcommand{\labelitemi}{$\diamond$}
The \leftmargini
through \leftmarginvi
parameters define
the distance between the left margin of the enclosing environment and
the left margin of the list. By convention, \leftmargin
is set
to the appropriate \leftmargin
N when a new level of
nesting is entered.
The defaults vary from ‘.5em’ (highest levels of nesting) to ‘2.5em’ (first level), and are a bit reduced in two-column mode. This example greatly reduces the margin space for outermost lists:
\setlength{\leftmargini}{1.25em} % default 2.5em
Some parameters that affect list formatting:
\itemindent
\labelsep
\labelwidth
\listparindent
\rightmargin
quote
,
quotation
, and verse
environments, where it is set equal
to \leftmargin
.
Parameters affecting vertical spacing between list items (rather loose, by default).
\itemsep
2pt plus1pt
minus1pt
for 10pt
documents, 3pt plus2pt minus1pt
for
11pt
, and 4.5pt plus2pt minus1pt
for 12pt
.
\parsep
\itemsep
.
\topsep
8pt plus2pt minus4pt
for
10pt
documents, 9pt plus3pt minus5pt
for 11pt
,
and 10pt plus4pt minus6pt
for 12pt
. These are reduced
for nested lists.
\partopsep
\topsep
when the list environment starts a
paragraph. The default is 2pt plus1pt minus1pt
for 10pt
documents, 3pt plus1pt minus1pt
for 11pt
, and 3pt
plus2pt minus2pt
for 12pt
.
Especially for lists with short items, it may be desirable to elide
space between items. Here is an example defining an itemize*
environment with no extra spacing between items, or between paragraphs
within a single item (\parskip
is not list-specific,
see \parskip):
\newenvironment{itemize*}% {\begin{itemize}% \setlength{\itemsep}{0pt}% \setlength{\parsep}{0pt}}% \setlength{\parskip}{0pt}}% {\end{itemize}}
