Dialog Programming Problem

Hi,

Can nebody tell me how do we go about designing screens like that of IW22.

e.g. Put a notification number and press ENTER.

Under Notification tab, there are different groupings Referece Object, Subject, Responsibilites etc.

It appears like a BLOCK of a selection screen.

How do we design such differentiations ? I thought frame might be the answer but it does not give this look.

What is this component used to club related elements ?

I got something related to Action Box in a standard prog but not sure.

Regards,

Nitin
