Is there a way to preview a subtable of a record in "list view"?

My colleague wants to quickly glimpse over an invoice from the “list view” without going into “form view” to check items of the subtable. How I make a subtable be seen in “list view”

Another idea would be like with the fly-in mouse hovering over a linked field. Is this possible?


Since one row is one record in listing page and subtable might contain more than one record, it’s not able to display subtable field value directly on listing page.

Maybe you can try create another general field and apply formula to sum subtable field value then show the general field on listing page.

I found a solution.
I made a parent sheet, then by linking a field of the invoices to that sheet’s id field, I can have the parent sheet show fly-in features.
