We are in need to hide slice values based on active property which is supported with slice measures but not with slice rows.
Please refer the following JSFiddle for further clarification.
Can you let us know the way to hide slice row values?
Thank you for writing to us.
We would like to inform you that
active property is available for measures only. That is the reason it works with measures only.
While working with rows, we kindly suggest adding and removing them from the slice. Please note that you can change the slice along with other report parts using the API call setReport(). To change only the slice use the runQuery() call.
Hope it helps.
