Cascading drop down lists
A cascading drop-down list is a series of dependent DropDownList controls in which one DropDownList control depends on the parent or previous DropDownList controls. The items in the DropDownList control are populated based on an item that is selected by the user from another DropDownList control.

For the purpose of this tutorial, I have used Geonames REST API to demonstrate this capability.
There are a number of organizations providing this kind of service and as long as they have well documented REST API’s you can easily integrate with AEM Forms using the data integration capability

The following steps were followed to implement cascading drop down lists in AEM Forms
