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 UserDefinedEnumerations.

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. Itaccepts 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:

(a)  one item
(b)  next item

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

You find more about \setupitemize at \defineitemgroup.
