Implementation notes
Update: 03/31/2023 - Updated focus states for accessibility.
1. Create a 🟨 Locations collection with all desired fields. Include Latitude & Longitude fields as plain text (not numbers).
2. Create a 🟨 Locations collection list on a static page. Apply the Location Item class to the collection items for later creating the locations array.
3. Create a hidden embed inside the collection item with any dynamic data you'd like to reference in the javascript. Latitude & Longitude coordinates are required for placing the location's pin & the slug for linking the collection to the pin's info window.
<div class="data---slug w-dyn-bind-empty">{{slug}}</div>
<div class="data---latitude w-dyn-bind-empty">{{latitude}}</div>
<div class="data---longitude w-dyn-bind-empty">{{longitude}}</div>
3.Create a hidden div inside the collection item named Data - Info Window & include all of the content you'd like in the map pin's info window.
4.Create an embed with the following javascript to open the pin's info window on click from the 🟨 Locations collection item. Then include & style any other data you'd like in the locations list.
<a href="javascript:google.maps.event.trigger(gmarkers['{{slug}}'],'click');" class="text-decoration---none"><div class="medium">{{name}}</div></a>
5. Include the Google Maps API script at the end of your page's body.
<script async defer src="https://maps.googleapis.com/maps/api/js?key[your-API-key]&callback=initMap" type="text/javascript"></script>
6. Include the map javascript between script tags after the Google Maps API script at the end of your page's body.

6.Create a div with the ID #map for the map to appear in. Position it as needed.
7. Customize the map styling with Google's Styling Wizard. Replace the json in the styles section of the javascript.
8. Treat yourself to a night on the town. You are done.
