Overview of commands

\startitemize

The most basic form of using enumerations in ConTeXt is

 \startitemize
 \item here we list the points,
 \item one after the other.
 \stopitemize

The \startitemize command takes optional parameters (see the documentation of \startitemgroup for a complete list), for example a number conversion may be given, with the following predefined types:

n or NUsually the default: a numbered list
mA numbered list, with lowercase (“medieval”, aka “oldstyle”) numbers.
18Different kinds of bullets. All items get the same symbol.
aItems are numbered a., b., c., …
AItems are numbered A., B., C., …
AKItems are numbered A., B., C., …, in small caps.
rItems are numbered in lowercase Roman numerals.
RItems are numbered in uppercase Roman numerals.
KRItems are numbered in uppercase Roman numerals, small caps style.

It is also possible to define your own number conversions; see User-Defined Enumerations. If you have loaded the Chinese module, you can also use c (and some more) for Chinese numbers.

When the selected language is Slovenian or Spanish, items are numbered using their proper alphabets (the Slovenian enumeration includes č, š and ž; the Spanish enumeration includes ñ). You can change to the international enumeration with alphabetic, Alphabetic.

Additional parameters include

\setupitemize

To change the general layout of enumerations, there is \setupitemize. It accepts an integer as its first parameter to denote for which level of itemization the subsequent settings should apply.

You will find more about \setupitemize at \setupitemgroup and \defineitemgroup.

\defineitemgroup

For finer control, it is advisable to create new types of itemization, using the command \defineitemgroup. For example:

  \defineitemgroup[ltxitm][levels=5]
  %
  \setupitemgroup[ltxitm][1][1]
  \setupitemgroup[ltxitm][2][2]
  \setupitemgroup[ltxitm][3][3,packed]
  \setupitemgroup[ltxitm][4][4,packed]
  \setupitemgroup[ltxitm][5][5,packed]
  %
  \starttext
  %
  \startltxitm
    \item Consider
      \startltxitm
      \item this part
      \item and also these subpoints:
        \startltxitm
        \item one
        \item two
        \item three
          \startltxitm
            \item threeandahalf
          \stopltxitm
        \item four
        \stopltxitm
      \stopltxitm
  \stopltxitm
  %
  \stoptext

Customization details and examples

Manual labels

\setupitemize[left=(, right=), margin=4em, stopper=]
\startitemize[a]
\item one item,
\item next item.
\stopitemize
  • margin is from left margin to start of item text
  • stopper is the dot (or whatever) after the "number"
\startitemize[R,fit][itemalign=flushright,stopper={ --- }]
\dorecurse{5}{\item blablabla}
\stopitemize

You can tell ConTeXt to begin item numbering at given offset [1]:

\startitemize[n,fit][start=42,stopper={\space}]
\dorecurse{3}{\item Lorem ipsum}
\stopitemize
Irregular item types can be inserted via \sym: \sym{#1} [2]:
\startitemize[a]
\item bar
\sym{1.}  foo
\sym{2.}  bar
\sym{3.}  foo
\sym{5.}  bar
\sym{8.}  foo
\sym{13.} bar
\item foo
\stopitemize

Note that the original (alphabetically enumerated) order is not affected by these insertions: it continues after the last one as if they didn't exist.

Expanded subnumbers

To specify that item numbers should also be leading numbers in any subitemizations, use the repeat keyword.

% Indentation is a bit odd; cannot reproduce off-wiki.

\setupitemgroup[itemize][1][n,repeat]
\setupitemgroup[itemize][2][a,repeat]
\setupitemgroup[itemize][3][n]

This is our item list:

\startitemize
    \item ...          % 1
    \startitemize
        \item ...      % 1.a
        \startitemize
            \item ...  % 1.a.1
        \stopitemize
        \item ...      % 1.b
        \startitemize
            \item ...  % 1.b.1
            \item ...  % 1.b.2
        \stopitemize
    \stopitemize
    \item ...          % 1
\stopitemize

To add change the separator mark, you have to setup the numberseparatorset key of the itemgroup:itemize counter. This example removes the separator mark entirely.

\setupitemgroup[itemize][1][n,repeat][width=1em]
\setupitemgroup[itemize][2][a,repeat][width=2em]
\setupitemgroup[itemize][3][n]       [width=3em]

\defineseparatorset[none][][]

\setupcounter[itemgroup:itemize][numberseparatorset=none]
\startitemize
    \item ...          % 1
    \startitemize
        \item ...      % 1a
        \startitemize
            \item ...  % 1a1
        \stopitemize
    \stopitemize
\stopitemize

Vertical spacing

This is the way how you can set spacing before and after itemize when working with

\setupwhitespace[big]

An option nowhite comes in handy:

paragraph before

\startitemize[joinedup,nowhite,after]
\item first
\item second
\stopitemize

paragraph after

These are all the four possible combinations of whitespace settings that you might want to use:



It is also (at least in mkiv) possible to do

Text before
\startitemize[before={\blank[small]},after={\blank[small]},inbetween={\blank[medium]}]
\item test
\item test
\stopitemize
Text after

to control the vertical space.


To prevent an unwanted pagebreak before the list, there is an intro parameter :

The following list is on the same page as this paragraph :
\startitemize[intro]
  \startitem foo \stopitem
  \startitem bar \stopitem
\stopitemize

Horizontal spacing

To control the space between the item symbol (bullet) and the item text

you can use eather the broad option

\startitemize[n*broad] %replace n with a number (e.g "3").
	\item Test
\stopitemize

or you can use absolute values (for fine tuning):

\startitemize[width=1em,distance=0pt]
	\item Test
\stopitemize

Multicolumn

Hans posted a solution to the list for a multicolumn enumeration that counts across then down, instead of down then across. When he posted it (Dec 21, 2005), he said the joinedup option does not work, but he would fix that. This is a version without the tufte and zapf text

\starttext

Some previous sentence before the list

\startitemize[columns,n,joinedup]
\item one
\item two
\stopitemize
\startitemize[continue,columns,joinedup]
\item one
\item two
\stopitemize
\startitemize[continue,columns,joinedup]
\item one
\item two
\stopitemize

And the text continues after the list

\stoptext

From a discussion on the mailing list, the following was suggested (note that you have to enclose your items in \startitem and \stopitem, using \item only does not work):

\starttext

Some previous sentence before the list

\startitemize[a,horizontal,three]
\startitem first \stopitem
\startitem second \stopitem
\startitem third \stopitem
\startitem fourth \stopitem
\startitem fifth \stopitem
\startitem sixth \stopitem
\stopitemize

And the text continues after the list

\stoptext

Other considerations

Randomizing items

It is possible to make ConTeXt randomize the items in enumerations; this can come handy when, e.g., typesetting tests. You have to add a random option to \startitemize. There are two caveats:

  1. You have to say \startitem ... \stopitem instead of \item ... .
  2. Somehow the first item does not get randomized. (I learned from the mailing list - thanks, Aditya! - that adding a \nextrandom somewhere earlier helps.)

Example:

\nextrandom
\startitemize[random]
\startitem A \stopitem
\startitem B \stopitem
\startitem C \stopitem
%\startitem F \stopitem
\stopitemize

Referring to items

You can also use a reference to an item, just like a chapter or section. See also References.

\starttext
\startitemize[n]
\item A
\item[foo] B
\item C
\stopitemize
\dots
As seen in \in{item}[foo] on page \at{page}[foo], B is teh shizzle.
\stoptext
