I'm using Leaflet with Omnivore plugin to show a KML file with multiple polygons. In this KML file there are 125 polygons. I want to pick only one to show on the map. The choice is made directly via the url (for example if I want to show the polygon named "Territorio 001" the url will be something like /map?n=001). Now, I can include, load and show the entire KML, but I can't figure out how I can "select" only one polygon to show, and hide the others.
