Please consider the idea to add the button option in popup window configuration tab to say that please hide all attribut table rows when the row value is <Null>, Empty ect
I know that I can create a arcade for that, but as it is quite widely asked thing maybe it is possible to provide central solution for that.
I do this all in Arcade because then I can leverage the HTML formatting to make a different-looking table, but it really does seem like something that should be included. Not everyone wants or has the time to deal with Arcade/HTML. Good idea!
