I am new to web programming here. I have a table which has multiple columns including: Restaurant Name,Restaurant Id, Lat, Lon, City, District, Country.
My problem is : I have to add dropdowns i.e. one for country, another for District /City based on the country selected. This city/district/country mapping has to come from the table which is in Teradata. Is there any way I can get the data to populate the dropdown from GeoServer services Or do I need to create a new service of my own. If I create my own service, can it be hosted from GeoServer.
