+#Extending
+
+To change how the front-end javascript displays the map the custom script with the unique id `locator_map_init_script`.
+This example shows how to reference custom templates and a custom data location. It is recommended to copy the custom script from the [Locator Controller](../../../code/pages/Locator.php#L273-L298) and modify it.
+
+```php
+$load = 'autoGeocode: false,  
+    fullMapStart: true,';
+$kilometer = ($this->owner->data()->Unit == 'km') ? "lengthUnit: 'km'" : "lengthUnit: 'm'";
+$modal = ($this->owner->data()->ModalWindow) ? 'modalWindow: true' : 'modalWindow: false';
+
+Requirements::customScript("
+    $(function(){
+        $('#map-container').storeLocator({
+            {$load}
+            dataLocation: '{$this->owner->Link()}SimpleXML.xml',
+            listTemplatePath: '{$this->listTemplate}',
+            infowindowTemplatePath: '{$this->windowTemplate}',
+            originMarker: true,
+            visibleMarkersList: false,
+            storeLimit: -1,
+            maxDistance: true,
+            slideMap: false,
+            distanceAlert: -1,
+            {$kilometer},
+            {$modal},
+            mapID: 'map',
+            locationList: 'loc-list',
+            mapSettings: {
+                zoom: 0,
+                mapTypeId: google.maps.MapTypeId.ROADMAP,
+                disableDoubleClickZoom: false,
+                scrollwheel: true,
+                navigationControl: false,
+                draggable: true
+            }
+        })
+    });",
+    "locator_map_init_script");
+}
+```
+
+Please note that this will replace the script that is loaded.
