If you've been kicking around the FileMaker neighborhood for any amount of time, you've probably run into a need to show multiple records in a list format as well as provide a detail view of the current record. Up until now you basically had two options.
The first and probably most popular method is to create one list view layout and another form view layout. The user typically performs a find and if there's more than one record found, you send them to an optimized list view layout. And then with the click of a button, they can see the related details of each record in a form view layout or even in a popover.
