A solution only by custom code (With/without webflow CMS) and google-maps API (or Mapbox).
It’s hard to give you an answer (This is more freelancer mission).
Also on mobile, you need another solution (Like your reference - the scroll changed to some slider).
Add click event (Go to #anchor X).
marker.addListener('click', function() {
/* do something*/
});
hello Louise,
would be great to discuss this in more detail, and figure out a way to implement a solution for you.
