< [[StructuralsBasics]]| [[Description]] > = Overview of commands = == \startitemize ==
The most basic form of using enumerations in ConTeXt is
</texcode>
The <{{cmd>|startitemize</cmd> }} command takes optional parameters (see the documentation of <{{cmd>|startitemgroup</cmd> }} for a complete list), for example a number conversion may be given, with the following predefined types:
<table>
</table>
It is also possible to define your own number conversions; see [[UserDefinedEnumerationsUser-Defined Enumerations]]. If you have loaded the [[Chinese]] module, you can also use <tt>c</tt> (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 <code>alphabetic</code>, <code>Alphabetic</code>.
Additional parameters include
* <tt>continue</tt> (start where the previous itemization was finished, to allow text injections),
* <tt>reverse</tt> (numbers the items in reverse, i.e. descending, order),* <tt>packed</tt> (less vertical space between items), and* <tt>inmargin</tt> (place enumeration symbols into the margin), and* <tt>text</tt> (paragraph enumerations, formats the items as a running text). == \setupitemize == To change the general layout of enumerations, there is {{cmd|setupitemize}}. It accepts an integer as its first parameter to denote for which level of itemization the subsequent settings should apply.
== \defineitemgroup == For finer control, it is advisable to create new types of itemization, using the command <{{cmd>|defineitemgroup</cmd> (which unfortunately seems undocumented)}}. For example, something similar to the LaTeX <tt>itemize</tt> environment can be defined as follows:
{| ! width="45%"| ! width="10%"| ! width="45%"| |- | <texcode>
\defineitemgroup[ltxitm][levels=5]
%
\stoptext
</texcode>
|gives | <context>
\defineitemgroup[ltxitm][levels=5]
%
\stoptext
</context>
|}
==Changing the Signs=Customization details and examples =
{| ! width="50%"| ! width="50%"| |- |<context>

\setupitemize[left=(, right=), margin=4em, stopper=]
\stoptext

| <texcode>
\setupitemize[left=(, right=), margin=4em, stopper=]
\startitemize[a]
\item one item,
\item next item.
\stopitemize
</texcode>
* <tt>margin</tt> is from left margin to start of item text
* <tt>stopper</tt> is the dot (or whatever) after the "number"

You can tell ConTeXt to begin item numbering at given offset [http://thread.gmane.org/gmane.comp.tex.context/61728/focus=61729]:
<texcode>
\startitemize[n,fit][start=42,stopper={\space}]
\dorecurse{3}{\item Lorem ipsum}
\stopitemize
</texcode>
|-
|<context>
\starttext
\startitemize[a,packed]
\item bar
\sym{1.} foo
\sym{2.} bar
\sym{3.} foo
\sym{5.} bar
\sym{8.} foo
\sym{13.} bar
\item foo
\stopitemize
\stoptext
</context>
|Irregular item types can be inserted via {{cmd|sym}}: <tt>\sym{#1}</tt> [http://article.gmane.org/gmane.comp.tex.context/61731]:
<texcode>
\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
</texcode>
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 {{code|repeat}} keyword.
<context source=yes>
% 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
</context>
To add change the separator mark, you have to setup the {{code|numberseparatorset}} key of the {{code|itemgroup:itemize}} counter. This example removes the separator mark entirely.
<context source=yes mode=mkiv>
\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
</context>
== Vertical spacing ==
This is the way how you must fill can set spacing before and after itemize when working with<cmdtexcode>setupitemize\setupwhitespace[big]</cmdtexcode> like this:
you can use eather the broad option
<texcode>
\startitemize[n*broad] %replace n with a number (e.g "3").
\item Test
\stopitemize
</texcode>
or you can use absolute values (for fine tuning):
<texcode>
\setupitemizestartitemize[leftwidth=1em,distance=(0pt] \item Test\stopitemize</texcode>||<context>\startitemize[width=1em, rightdistance=)0pt] \item Using width=1em, margindistance=0pt\stopitemize\setuplayout[scale=4em0.8, stopperwidth=9cm]\startitemize \item {\bf Default} (no arguments)\stopitemize \startitemize[1*broad] \item Using 1*broad\stopitemize\startitemize[3*broad] \item Using 2*broad\stopitemize</context>|} ==Multicolumn== Hans posted asolution 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 {| ! width="45%"| ! width="10%"| ! width="45%"| |- | <texcode>\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</texcode>||<context>\starttext Some previous sentence before the list \startitemize[columns,n,joinedup]\item one\item two\stopitemize\startitemize[continue,columns,joinedup]\item one \itemtwo\stopitemize\startitemize[continue,columns,joinedup]\item one\item next two\stopitemize And the text continues after the list \stoptext </context>|} From a discussion on the mailing list, the following was suggested (note that you have to enclose your items in <cmd>startitem</cmd> and <cmd>stopitem</cmd>, using <cmd>item</cmd> only does not work): {| ! width="35%"| ! width="5%"| ! width="60%"| |- | <texcode>\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</texcode>||<context>\starttext Some previous sentence before the list \startitemize[a,horizontal,two]\startitem first \stopitem\startitem second \stopitem\startitem third \stopitem\startitem fourth \stopitem\stopitemize And the text continues after the list \stoptext </context>|} = 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 <tt>random</tt> option to <cmd>startitemize</cmd>. There are two caveats:# You have to say <cmd>startitem</cmd> ... <cmd>stopitem</cmd> instead of <cmd>item</cmd> ... .# Somehow the first item does not get randomized. (I learned from the mailing list - thanks, Aditya! - that adding a <cmd>nextrandom</cmd> somewhere earlier helps.)Example: {| ! width="45%"| ! width="10%"| ! width="45%"| |- | <texcode>\nextrandom\startitemize[random]\startitem A \stopitem\startitem B \stopitem\startitem C \stopitem%\startitem F \stopitem\stopitemize</texcode>|| <context>\nextrandom\startitemize[random]\startitem A \stopitem\startitem B \stopitem\startitem C \stopitem%\startitem F \stopitem\stopitemize</context>|} == Referring to items ==You can also use a reference to an item, just like a chapter or section. See also [[References]]. {| ! width="45%"| ! width="10%"| ! width="45%"| |- | <texcode>\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.
