I have a question. I added a custom post type, and there created object A, then I created another object B. What should I do if the object A and the object B have the same address? The map shows only one marker when several objects can be attached to this one address.
I know only this solution – https://github.com/jawj/OverlappingMarkerSpiderfier, it is possible to apply something like this in future updates?
This problem is most apparent on a map with category filtering, when one object with the same address can be in different categories, and when all categories are selected, only one marker of a particular object is displayed.
Yeah, you are right if you have multiple addresses with the same location then your all markers categories markers are overlapped with each other and displayed only single marker at the frontend but according to select the category your marker will be change.
Can you send me your page URL so I can also check it at your end? You need to set a zoom level according to map needs. I don't think your all restaurants categories location have the same address.
If you are using the same address for the different locations the marker will be overlapped with each other and top marker will be displayed only. So this is not possible to display all markers in a single location.
