Drill down grouped report - how to show group detail column headers only when group is expanded
I have a simple drill down grouped report with a group header followed by a master data band.
The group header has some memos with summary group data and the master band below it has some memos showing data from items within that group.
To make some column headers for the individual items I put some memos with plain text in them at the bottom of the group header, lined up vertically with where the individual data in the master band will appear.
This works fine when the group is expanded but looks strange when I collapse the group as obviously I still see the column headers (along with the summary group data), even though I can't see the expanded data.
Is there a better way to make column headers for the expanded data such that they only appear for that group when the data itself if expanded?
