Q: How to place description on each map marker
A:
- Modify SQL Query to create a calculated field with custom name and address.
SELECT
CustomerID,
CompanyName,
ContactName,
ContactTitle,
Address,
Lat,
Lng,
concat(ContactName, '\n', Address) as DisplayOnMap
FROM customers
Notice '\n', it allows us to create multiline descriptions. concat() function is MySQL specific. Similar functions exist in all databases.

2. Insert a map into List page. Here are settings I have used for this specific table.
// Longitude and latitude or address field should be specified
// name of field in table that used as address for map
$mapSettings["addressField"] = "DisplayOnMap";
// name of field in table that used as latitude for map
$mapSettings["latField"] = "Lat";
// name of field in table that used as longitude for map
$mapSettings["lngField"] = "Lng";
Latitude and Longitude fields are required as we use address field for marker description purposes.
