Hi again, I had the problem that my chapters always started on a left page, even if I just had page=yes. I found out I had to set page=no in my columnset as well as in \setuphead[chapter]. Seems like either the columnset or the columnsetspan always starts a new page. While testing I didn’t get a new page reliably, but I can’t reproduce it anymore. So, this works so far. I’m starting a new columnset for every chapter because I have chapters with 1-3 columns, the example is a simplification. HR \usemodule[visual] \setuppapersize[A5] \showframe[text] \definecolor[fakerulecolor][gray] \setuplayout[ grid=yes, ] \showgrid \setuphead[chapter][ page=no, beforesection={\startcolumnset[Two]}, aftersection={\stopcolumnset}, before={\startcolumnsetspan[TwoSpan]}, after={\stopcolumnsetspan}, ] \definecolumnset[Two][ n=2, page=no, ] \definecolumnsetspan[TwoSpan][n=2] \starttext \dorecurse{3}{ \startchapter{\fakewords{2}{5}} \dorecurse{3}{ \section{\fakewords{3}{10}} \fakewords{10}{50}\par \fakewords{10}{50}\par } \stopchapter } \stoptext
