If you don't want to link it with the 'click' event, can you please share information about selecting the highlighted map marker? I'll be in a better position to guide you, accordingly.
Hi, my page uses a content template which shows a single CPT listing. Within that template i have a view which shows several listings from the same CPT. How do I pull the ID of the single listing into the view to differentiate the map icon from all the others
You can check the option "Don't include current page in query result" in the view's "Query Options", which will exclude the marker from the current post from showing.
Next, you can include a separate instance of the "wpv-map-marker" shortcode with a different/special marker icon, for the current post in the template directly, so that it is not in the view's loop.
This way, the results from the view will show the map markers with the default marker icon, while the map marker for the current post will show with a different/special marker icon.
