Command/head

Syntax

\head ... \par
\starthead[ref,ref,...]{Title} ... \stophead
[ref,ref,...]

Description

Used in itemizations. Prints the first paragraph of an item in the headstyle specified in \startitemize, and prevents a pagebreak from occurring between the head and the next item. By default, the headstyle is simply the normal style. A \par after a \head is required, so that ConTeXt may distinguish between the header line and the rest of the head item.

Because the occasional bold item in a list still does not look very much like a head, the items under the head are often printed in a nested \startitemize.

Referring to the head

The syntax \head[ref] does not work - it is necessary to use \starthead[ref] ... \stophead

Example

\startitemize[packed][headstyle=bold]
    \head Birds \par
        What is water? This is a difficult question to answer, 
        because water is impossible to define. One could ask 
        the same question about birds. What {\em are} birds? 
        We just don't know.
        \startitemize[a]
            \item Toucan
            \item Quetzal
            \item Cassowary
        \stopitemize

    \head Mammals \par 
        \startitemize[continue]
            \item Anteater
            \item Sloth
            \item Capybara
        \stopitemize
\stopitemize

In LMTX, the preferred syntax is:

\startitemize[packed, headintext][headcolor=red]
    \starthead{Birds} 
    What is water? This is a difficult question to answer. 
    \stophead
\stopitemize

Example of a reference

  \startitemize[i][stopper=),headstyle=bold]
    \item[TheItem] Item

    \starthead[TheHead]{Head}

      Some text

    \stophead
  \stopitemize

  See point \in[TheItem] or \in[TheHead].
