Is there any way to integrate Meta Box map with wpgridbuilder map facet like they do with ACF?
They say in that link that the custom field should output an array:
The Map facet works with latitude and longitude coordinates. The source type should be a custom field with as value an array containing the coordinates like this:
[ 'lat' => 5.1025, 'lng' => 40.5548 ]
Can you help?
