The following map shows some of what you can do with the Map User Item in Second Site. The initial location and zoom level are chosen by the user. In this case, that view includes three markers for cemetery locations. Those were created using Second Site's Map Editor.
You can open a marker by clicking the marker itself, or clicking the marker's name in the list on the left. When you click the list entry, that will scroll the marker into view if it is not in view already.
Click the Lunenburg link to scroll the map so that Lunenburg, Nova Scotia is visible. That shows an example of a marker created from TMG events: two events that occurred at the same place.
You can add one or more maps to any Custom Page, and you can mix maps with other User Items.
