[NTG-context] Linebreak between Chapter Number and Name

Hi, I am trying to format a chapter heading so that there is a linebreak between the number and the name. The only way I managed to do this is this: \setuphead[ chapter][command=\ChapTitle] \def\ChapTitle#1#2% {\framed[height=2cm,width=broad]{#1\\#2} } But this limits me to a fixed height for the frame. This doesn't work if I don't set a fixed height, which would be a problem with longer chapter names that need linebreaks. What is the correct way to do this? Thank you, Marc Trius.
