I understand there is a bug that prevents WAB attribute widget to use the configuration of the popup window in the Web Map, while the popup is disabled. Thus, while this is corrected by WAB development team, I need code to show the thousand separator for numeric fields in the attribute widget. Any suggestions from experts in Web AppBuilder Developer Edition? Thanks in advanced!
PS: although I understand HTML/CSS/JS and might be able to perform minor modifications, this is clearly above my skills.
