Hi all,
Considering the fact that I have no answer for the thread 
"[NTG-context] Presentation style: customizing the right interaction 
menu (list-related thread)", I decided to reformulate my problem...
After some experiments, I have the following code:
\definehead [Topic]   [chapter]
\definehead [Subject] [section]
\setuplist[Topic][alternative=f,criterium=all,align=left]
\setuplist[Subject][alternative=f,criterium=chapter,align=left]
\starttext
\Topic{Topic 1}
\Subject{Subject 1}
\Subject{Subject 2}
\Subject{Subject 3}
\placelist[Topic,Subject]
\Topic{Topic 2}
\Subject{Subject 1}
\Subject{Subject 2}
\Subject{Subject 3}
\stoptext
Considering the fact that I use criterium=chapter in 
\setuplist[Subject], I thought that \placelist[Topic,Subject] leads to:
Topic 1
Subject 1
Subject 2
Subject 3
Topic 2
but unfortunately, that's not the case and I don't understand why... 
I've also tried some setup with combinedlist but nothing works... 
Could someone explain why criterium as no effect... Moreover, I don't 
understand what coupling= on|off does...
maybe future version of context will provide more control; for the moment, stick to:  


\definehead [Topic]   [chapter]
\definehead [Subject] [section]

\newcounter\MyTopicCounter

\startsetups MyTopicList
    \blank
    \doglobal\increment\MyTopicCounter
    \doglobal\newcounter\MySubjectCounter
    \placelist[Topic][criterium=text,after=\setups{MySubjectList}]
\stopsetups
\startsetups MySubjectList
    \doglobal\increment\MySubjectCounter
    \doifelse{\MyTopicCounter}{\MySubjectCounter} {
        \placelist[Subject]
    } {
        % whatever
    }
\stopsetups

\starttext

\Topic{first}  \Subject{one}   test \Subject{two}  test \setups[MyTopicList] \page
\Topic{second} \Subject{alpha} test \Subject{beta} test \setups[MyTopicList] \page

\stoptext
