Need help showing a table of Accounts under each Location in a hierarchical table in VBS.

Summary:

As per our business requirement, we are developing a hierarchical Tree Table in Oracle Visual Builder Studio (VBS). The structure we are aiming for is:

Output

Locations

Accounts

We are currently using <oj-row-expander> to successfully render Outputs and Locations. However, we are struggling to render a table of Accounts under each Location.

The issue is that VBS doesn't seem to support adding a nested oj-table (Accounts) inside an already expanded Location row using standard component features or documented methods.

We would like to know:

Is it technically supported to embed a table under an already expanded row (i.e., a second level of expansion or custom nested table)?
