[NTG-context] Table of contents, alternative d

Hi all, Am using the alternative d for my table of contents, i know how to align my elements left (from the left margin) but can't manage to do that at the right side (from the right margin). This is how i configure things: \definelist[part] \setuplist[part][before={\blank[big]},after=\blank] % \definelist[chapter] \setuplist[chapter][alternative=d,margin=2cm,left=(,right=),depth=2cm,before=\blank,after=\blank,style=Opulent] \placecontent[level=chapter] Any help .. Thanks. Dirar.
