WpCasa Map, avoid fitBounds() Zoom too close for single marker

Question

Looking at this question Google Maps v3 fitBounds() Zoom too close for single marker

seems the easy way is to pass maxZoom option

var map = new google.maps.Map(document.getElementById("map"), { maxZoom: 14 });

Looking at the source code of the plugin, seems there is a hook for that wpsight_listings_map_options

Now I'm confused on how to use the hook.

Answer 1

Turns out I found my way... and perhaps it could help others.

Here is what I've added to functions.php

add_filter( 'wpsight_listings_map_options', 'wpsight_listings_maxZoom' );
function wpsight_listings_maxZoom( $opt ) { 

  $opt['map']['maxZoom'] = 16;

  return $opt;

}
