Hello,
Thank you for your solution that works on the proposed example, but that
does not work on a more complex example.
Fabrice

\definemixedcolumns
  [Mycolumns]
  [
    n=2,
    separator=rule,
    rulecolor=,
    balance=,
    grid=strut,
  ]

\setupalign[verytolerant,stretch,hanging]

\setuppapersize[A4,landscape]
\setupinteractionscreen[option=landscape]

\starttext
  \startMycolumns
    \startitemize[n]
      \startitem
        One
      \stopitem
      \startitem
    \startitemize[a,packed, horizontal, three]
      \startitem
        \math{Q_1\approx -8}
      \stopitem
      \startitem
         \math{M_e\approx 22}
       \stopitem
       \startitem
         \math{Q_3\approx 40}
      \stopitem
    \stopitemize
      \stopitem
    \stopitem
    \stopitemize
  \stopMycolumns
\stoptext
