How to implement rollup functionality in OTBI / BIP report in Oracle CX Sales Fusion?

Hi everyone,

I’m exploring whether Oracle OTBI (Oracle Transactional Business Intelligence) or BI Publisher can support a report layout similar to the Rollup (expand/collapse) functionality available in Oracle RightNow / Oracle Service Cloud Analytics.

Business Context:

In RightNow, reports can use rollups, where grouped data is displayed in collapsible horizontal sections. Users can expand or collapse a certain field.
I’ve attached a screenshot showing how each product type (e.g., “Product Type: DOM Holiday FIT,” “Product Type: INT Holiday FIT”) can be expanded/collapsed dynamically. I want to achieve the same in Oracle CX Sales Fusion.
