I'm trying to customize the behaviour of the default popup window inside a WAB application.
I've found a really impressive work by Nick (link below) that customize the behaviour perfectly, but I spent a very long time trying to make it work with a webmap / map service rather than single layers with no success..
The first and most important customization I'm trying to achieve is to make the popup window remain opened until the user manually close it (multiple popup windows).
Has anyone ever done this before with a map service rather than a map layer object? it seems to behave very differently and the selected features are not saved globally.
