Hello,

here is a simple code:

----
\definedescription[Mat]
   [headstyle=bi,
    
text={Foo},alternative=serried,width_=fit,indenting_={yes,medium},indenting_=no,align_=left,indentnext_=no,hang_=none,
   ]

\starttext

   \startMat
     \startitemize[packed,][]
       \starttabulate[|l|l|l|]
         \NI Aaa \NC Aa \NC\AR
         \NI Bbb \NC Bb \NC\AR
       \stoptabulate
     \stopitemize
   \stopMat

   \startMat
     \startitemize[packed_,joinedup_][afterhead=,]
       \head Ttt \par
         Tt

       \head Uuu \par
         Uu
     \stopitemize
   \stopMat

\stoptext
----

which produces something like:

Foo
   • Aaa Aa
   • Bbb Bb

Foo
• Ttt
Tt
• Uuu
Uu


I cannot find out how to arrange the tabulate bullets straight above 
those of itemize, so how to supress the left indeting, to get:

Foo
• Aaa Aa
• Bbb Bb

Foo
• Ttt
Tt
• Uuu
Uu

How do I achieve this?

TIA.

Best regards,

Lukas
