The following code does not hide the headings: \setuphead[subsection][ placehead=no, number=no, ] % placehead=hidden breaks the counters? \setuphead[subsubsection][ placehead=no, number=no, ] \starttext \chapter{chapter} chapter \section{section} section \section{subsection} subsection \section{subsubsection} subsubsection \stoptext The following code also does not hide the headings: % placehead=hidden breaks the counters? \setuphead[subsection, subsubsection][ placehead=no, number=no, ] \starttext \chapter{chapter} chapter \section{section} section \section{subsection} subsection \section{subsubsection} subsubsection \stoptext However, adding "section" makes the sub- and subsubsections hide as expected: \setuphead[section, subsection, subsubsection][ placehead=no, number=no, ] \starttext \chapter{chapter} chapter \section{section} section \section{subsection} subsection \section{subsubsection} subsubsection \stoptext This behaviour appears to violate the principle of least astonishment.
