Hey,
I am still looking for a solution how to use an off-panel widget with the integrated Web AppBuilder in Portal for ArcGIS.
Adding in-panel Widgets works fine since 10.5.1 and adding an off-panel Widget to Web AppBuilder for Developer also works fine by editing the config.json.
But how to bring an off-panel Widget to the integrated Web AppBuilder at all?
How to make sure that an Hotfix / Patch / Upgrade is not going to revert the changes?
Best,
Stefan
