Some frontend javascript using the Query .fadein like this:
$(selector).fadeIn(duration,complete) → jQuery
$(selector).fadeIn(options) → jQuery
$(selector).fadeIn(duration,easing,complete) → jQuery
Trigger it after pagecompletion like Warren described in his comment in https://forum.mendix.com/link/questions/96827:
"I also discovered you can also achieve it by adding an empty (but "visible (although it doesn't show)) data view who's data source is the mf you want to call." Warren Gay
