Lillie, thank you for the response. I don’t think that is what I need. In my example, Referral Source, Case Category and Case Type are all in the Rows Field Well. If you are familiar with webdatarocks it would work more like Pivot Tables in webdatarocks (https://codepen.io/webdatarocks/pen/dLeZvN). Notice how the rows are stacked in column 1 at the bottom.
I think what you are looking for is the ability to stack all of the row fields into a single column that you can expand and collapse within that column. That is what I noticed in the webdatarocks example and is what I think you are getting at with the drawing above. This is a feature that we do not currently have in QuickSight currently, but it is a feature we do have on our roadmap.
