Can anybody help me with this - I want a Filter/Select option for entire application ( if I select a country I want that on all my app pages/screens to see information only from that country ).
I know about “In-app Filter” but I can use it on each individual page/screen.
Your solution is ok, but for me the country is not linked to the user but to the event (events must be filtered according to the country and you don’t have to be logged into the application to see the events).
As you mentioned, your case is not a multi-filter scenario and doesn’t require such a complex process. In the example, you simply apply filtering based on the selected country name, so that all components in pages are filtered according to the corresponding data from the single value pulled from the helper table.
The key is that all tables you want to filter should have a country name column, and the single value will be used as the basis for filtering in your collection components.
