Oh it's great ! that's what I need ! big thanks
It is possible to make the same things, but with multiple data source or it's limited to 2 data sources ?
To return to my previous exemple : I select one society on my List (Source1), it select/filter the building where the society is on my Map Widget (Source 2) and the application select in a Table Widget the information of Transaction (Source 3). It is possible to do that ?
