ConTeXt: How to keep title and table of contents on the same page

Question

How can I tell ConTeXt not to insert a page break before \completecontent? I'm trying to keep A title on the same page as the table of contents:

\starttext

  \startfrontmatter
    A title
    \completecontent
  \stopfrontmatter

  \startbodymatter

    \startchapter [title=Foo]
    \stopchapter

  \stopbodymatter

\stoptext

Answer 1

The \completecontent command uses \title to place the the title for the table of contents. To get rid of the pagebreak at the start of it you can either disable the pagebreak with

\setuphead
  [title]
  [page=no]

but this isn't recommended because the setting affects all \title commands. While it is possible to limit the setup to the frontmatter a better solution is to create a new heading

\definehead
  [contenttitle]
  [title]

and disable the pagebreak onl for this heading

\setuphead
  [contenttitle]
  [page=no]

The next is is to remove the \completecontent command from your document and replace it with a combination of the new heading followed by a table of contents without the automatic title.

\contenttitle{\headtext{content}}
\placecontent

With \headtext{content} you can access the language dependant title for the table of contents but there is nothing wrong to set a fixed text instead (\contenttitle{Contents}).

Answer 2

Although it isn't perfectly explicit about this, the Wiki (https://wiki.contextgarden.net/Table_of_Contents) suggests the following:

\completecontent % with title
\placecontent % without title

You should find that replacing \completecontent with \placecontent will do the trick.
