Hello Jaroslav,
I have something like the following which was given to me by Hans a long time
ago: unfortunately for some reason this does not work anymore with ConTeXt
mkiv, but it is quite fine with mkii:
%%% begin question-hint-answer.tex
\defineblock[question]
\defineblock[hint]
\defineblock[answer]
\defineenumeration[question][location=hanging,text={Question},stopper={.}]
\defineenumeration[hint][location=hanging,text={Hint for question},stopper={.}]
\defineenumeration[answer][location=hanging,text={Answer to
question},stopper={.}]
\hideblocks[hint]
\hideblocks[answer]
\starttext
\section{Questions}
\beginquestion
\question Compute $4\times 5$.
\beginhint
\hint Use the fact that $2\times 5 = 10$.
\endhint
\beginanswer
\answer $20$.
\endanswer
\endquestion
\beginquestion
\question What is the value of $100 / 10$?
\beginhint
\hint Remember that $10\times 10 = 100$.
\endhint
\beginanswer
\answer $10$
\endanswer
\endquestion
\section{Hints}
\useblocks[hint]
\section{Answers}
\useblocks[answer]
\stoptext
%%% end question-hint-answer.tex
Best regards: OK
