I thought there should be a setups key on \setupsectionblock, but apparently there isn’t. So, the example below does not work, but maybe it wouldn’t be too hard to add it…

There is a ‘before' key, but note that the sectionblock itself is called “backpart”, not “backmatter”

Either use

\setupsectionblock[backpart][before={\setuphead[chapter][page=no]}]

Or, nicer:

\startsectionblockenvironment[backpart]
  \setuphead[chapter][page=no]
\stopsectionblockenvironment

 Best,

  \setuphead[chapter][page=yes]

Betreff: [NTG-context] Chapters without new page
 In the \startbackmatter ... \stopbackmatter section i would like to have some chapters that are not automatically placed on a new page for the next chapter. Is there an easy way to suppress the new page for these chapters?
Thanks, Jeroen

Best wishes,
Taco

While this works, it changes behavior for **all** chapters. It does not address the original question of how to have **some** chapters  "not automatically placed on a new page."
