Included are a summary template for mapping the points, a category template for creating the group toggles (see layers icon at the top right of the map) and a detail template. Sample data and fields are also included, easily replaced with your own information.
Map pins include a popup you can customize with your own field definitions and html, including images. There are many more features available in Leaflet such as changing base maps, customizing pin icons, etc. These are not included in this instance but can easily be added by a competent developer.
