I was able to configure popups in my web map using ArcGIS. This included styling and divs. However when I pull the map into Portal using WAB 2.1, the styling and div classes are stripped leaving me with a bunch of messy text. These popups look great in ArcGIS Online, and they include tabs and tables styled to the way I like. The styling doesn't remain however once the map has been pulled into WAB 2.1.
Has anyone out there come across a solution to this?
