All, We are currently using this as one of our environment files: \definehead[unnumberedsubsection][subsection] \setuphead[unnumberedsubsection][number=no,incrementnumber=no] \defineenumeration[questions][location=serried,text=\blank] \setupenumerations[questions][before={\page[yes]\unnumberedsubsection {Exercises}\startcolumns[n=2]},after=\stopcolumns,number=no] \defineenumeration[answers][location=serried,text=\blank] \setupenumerations[answers][before={\unnumberedsubsection{Answers} \startcolumns[n=2]},after=\stopcolumns,number=no] \def\placeanswers{\startanswers\doifmodeelse{short}{\selectblocks [shortanswer][criterium=section]}{\selectblocks[longanswer] [criterium=section]}\stopanswers} \defineenumeration[question][location=inleft,text={\color[heavygreen] \bgroup}] \setupenumerations [question] [location=inleft, text={\color[heavygreen]\bgroup}, stopper={.\egroup}, way=bysection, sectionnumber=no] \defineenumeration[subquestion][location=hanging,text={\color [heavygreen]\bgroup},conversion=characters] \setupenumerations[subquestion][stopper={.\egroup}] \defineenumeration[answer][location=inleft,text={\color[heavygreen] \bgroup}] \setupenumerations [answer] [location=inleft, text={\color[heavygreen]\bgroup}, stopper={.\egroup}, way=bysection, sectionnumber=no] \defineenumeration[subanswer][location=hanging,text={\color [heavygreen]\bgroup},conversion=characters] \setupenumerations[subanswer][stopper={.\egroup}] \defineblock[question,shortanswer,longanswer] \hideblocks[shortanswer,longanswer] Then we do something like: \beginquestion \starquestion Yada, yada, yada. \startsubquestion one part \stopsubquestion \startsubquestion part a \stopsubquestion \startsubquestion part b \stopsubquestion \stopquestion \endquestion Then we have some answers. \beginlonganswer \startanswer \startsubanswer part a \stopsubanswer \startsubanswer part b \stopsubanswer \stopanswer \endlonganswer I'd like to set it up so we could "hide" some subanswers. Any suggestions?
