I'm trying to show a map with multiple markers with the help of Views and Geolocation field. It would be nice for example if I can show the image in the tooltip display of the marker. But when I add an image as a field to achieve this, the image automatically gets selected as the icon source field by default (See Views UI - FORMAT - Advanced settings). Is it possible change this behavior?
You need to create a display in your content type where you will put the field that you want to show in the tooltip.
Home » Administration » Structure » Content types » YOUR CONTENT TYPE » Manage display
Then in your view select in the format to show Content and in the View mode the display that you created before with your fields.
