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. An empty line or 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.
Example
\startitemize[packed][headstyle=bold] \head Birds % empty line is required between first par and rest of head % item, or one will get a very long header 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 % The \par has the same function as the empty line \startitemize[continue] \item Anteater \item Sloth \item Capybara \stopitemize \stopitemize
