Iâve found lots of code for how to add custom markers to Google Maps, but hardly anything about using different markers on the same map. For instance, I may have 4 markers from an Advanced Custom Fields repeater field that I want to appear with a green marker, and the rest of the markers related to a custom post type to appear with a gray marker.
Iâve tried a few different methods, like duplicating the marker variable and changing the name and colors, but everything I try breaks some part of the map.
Here’s a screenshot of the two different types of map markers I need: http://screencast.com/t/Cc5eE7St
The code below works, but it’s all one type of marker.
<style type="text/css">
.acf-map {
width: 100%;
height: 730px;
}
/* fixes potential theme css conflict */
.acf-map img {
max-width: inherit !important;
}
</style>

Charlotte, you could add a “data-marker” attribute to each of your marker objects as you build the markup, like this (green/grey wherever you need them)
And then in the javascript you can check the marker type using the data-marker you set in the code, like this
