Usage

In order to use leaflet on your page, It is required to include the following vendors css in the "Vendors CSS" area from the page's header:

<link rel="stylesheet" href="assets/vendor/libs/leaflet/leaflet.css" />

Include the following vendors script in the "Vendors JS" area from the page's footer:

<script src="assets/vendor/libs/leaflet/leaflet.js" />

Basic

<div class="leaflet-map" id="basicMap"></div>

const basicMap = L.map('basicMap').setView([42.35, -71.08], 10);
L.tileLayer('https://{s}.tile.osm.org/{z}/{x}/{y}.png', {
  attribution: 'Map data &copy; <a href="https://www.openstreetmap.org/">OpenStreetMap</a>',
  maxZoom: 18
}).addTo(basicMap);

Marker Shapes

<div class="leaflet-map" id="shapeMap"></div>

const markerMap = L.map('shapeMap').setView([51.5, -0.09], 12);
const marker = L.marker([51.5, -0.09]).addTo(markerMap);
const circle = L.circle([51.508, -0.11], {
  color: 'red',
  fillColor: '#f03',
  fillOpacity: 0.5,
  radius: 500
}).addTo(markerMap);
const polygon = L.polygon([
  [51.509, -0.08],
  [51.503, -0.06],
  [51.51, -0.047]
]).addTo(markerMap);
L.tileLayer('https://{s}.tile.osm.org/{z}/{x}/{y}.png', {
