I have a map with the Area Layer and I would like to be able to select a single country but still be able to see all other countries that were originally on the map. Reading the community forum I found only posts suggesting the following:
go to the field setting
select "always one selected value"
but it doesn't work like I need. Please have a look at the example blow.
Here is the initial state: a map with some areas.
When I select the "always one selected value" checkbox and click on a country then all other countries are removed from the map. This is wrong, I don't want it to work like that.
When the "always one selected value" checkbox is not selected then counties are not removed from the map but I can select more than one country. This is wrong, I don't want it to work like that.
Ideally, I would like to have the selected country highlighted with a color and all other countries turned gray.
When I select other country then it gets highlighted and all other countries turn gray.
