For this we often set [maxwidth=...] in menus or lists.

\unexpanded\def\titles%
  {\doquintuplegroupempty\dotitles}

\def\dotitles#1#2#3#4#5%
  {\ifcase\titlelevel\or
     #1\or#2\or#3\or#4\or#5\else wrong level%
   \fi}

\def\titlelevel{1}

\starttext

{\def\titlelevel{2}\placelist[section]}
{\def\titlelevel{3}\placelist[section]}

\section{\titles{one}{first}{dit is de eerste}}
\section{\titles{two}{second}{en dit de tweede}}
\section{\titles{three}{third}{vooruit, een derde}}

\stoptext

I can think of cooking this into the head mechanism [a similar mechanism is
present in references, where one can have more that just a simple ref].
