Hello J,
You can use a List item bound to a data object with as many records as sub reports you want to display. The List item's data source can be controlled by the parameter defining the number of sub reports.
In the List item you can add a SubReport item that will display the sub report, where values can be sent to sub report parameter's by accessing the container's data with an expression like
=ReportItem.DataObject.FieldX, or
=ReportItem.Parent.DataObject.FieldX. The
Parent keyword gets the parent element's scope.
The List item can grow vertically or horizontally (there is a 'Rotate Layout' option in its Context Menu). You can also add proper groupings changing the positions of the visualized content e.g.
How to: Create Multi-Column Report - Across the Page and Then Down.
I hope this information is helpful.
Regards,
Stef
