[NTG-context] Q: indenting a table of contents

I would like a table of contents to be indented as: 1.1 First Section 1.1.1 First Subsection of First Section 1.1.1.2 .... 1.1.2 hjfhkdsf For a first approximation I used \setuplist [section] [width=2em,distance=1em] \setuplist [subsection] [margin=3em,width=3em,distance=1em] \setuplist [subsubsection] [margin=7em,width=3em,distance=1em] This is not satisfactory, since the distance between the numbers and the title varies for different levels. If I use width=fit, can I access the computed width for the previous level to set up a list? Or is there already an option to achieve this? Thanks in advance Marko
