I have a map with polygons vector objects.
Superpositions can exist between the polygons. That is to say a bigger polygon is sometimes completely above a smaller one.
With Openlayers, is it possible to display two pop-ups instead of only one (the 1st pop-up being related to the polygon above, the 2nd being related to the polygon on the bottom) ? Or one pop-up containing the attributes of the two polygons ?
I looked for infos but didn't find a lot of stuff on that. There is that subject (https://stackoverflow.com/questions/43859364/display-multiple-wfs-layers-with-popup) but no answers.
