I have a list of Contracts.
A Contract relates to a specific territorial area (one or more set of polygon coordinates).
I want to be able to select a Contract and update the polygons that are being displayed.
So far all I have managed to be able to do is get the map to reload. This seems unnecessary as the map is not changing it is the query with the polygons that is changing.
Is there a way to leave the map as is but only change the polygons being displayed?
