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.

Additional parameters include

  • continue (start where the previous itemization was finished, to allow text injections),
  • packed (less vertical space between items), and
  • inmargin (place enumeration symbols into the margin).

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. There is an example below.

For finer control, it is advisable to create new types of itemization, using the command \defineitemgroup (which unfortunately seems undocumented). For example, something similar to the LaTeX itemize environment can be defined as follows:

  \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

gives

Changing the Signs

For a enumeration like this:

you must fill \setupitemize like this:

  • you get parentheses by left=(, right=)
  • margin is from left margin to start of item text
  • stopper is the dot (or whatever) after the "number"
\setupitemize[left=(, right=), margin=4em, stopper=]
\startitemize[a]
\item one item,
\item next item.
\stopitemize

You find more about \setupitemize at \defineitemgroup.


Alternate Multicolumn Format

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
