After a couple of hours of experimentation I discovered the easiest way to achieve detail band vertical overflow.
Technically speaking the detail band overflow is not achievable. But By Creating a Dummy Group and making the group repeat for all the records and placing it below all other groups you can get the desired result. Here’s the steps you need to take.
- Create a Dummy Group
- Place it after all other groups
- Put a unique key as the “Group Expression” (This way for each record will create a new group)
- Put your display fields in the group header and remove the details section
