Drop group heading to first row only

[Tom Corcoran]

I am using BIRT rcp 2.3.1. I am have rows with multiple entries for the first column name and want to only show the name when it changes. Looking at pg 214 of the field guide book it I can add a group on the name, which works. However I want to drop the name only when it changes. To do this it says in the property editor general page set drop to detail. however in the current rcp, I can't find this drop option. Can anyone help.

Thanks, Tom.
