[NTG-context] table of contents

Is there a simple manner to restrict the table of contents to chapter and section, excluding subsections, subsubsections? Now I use (and get all) \startfrontmatter% the table of contents \setuppagenumber[number=1,numberconversion=romannumerals] \completecontent \stopfrontmatter I tried \completecontent[criterium={chapter,section}] bat that doesn't work. Could not find it on the wiki, but I might have missed the right search term. Hans van der Meer
