Standardised Schema
If you would like to use a merge or cascade locator with the Drilldown widget then you will need to set them up using a standardised schema that matches one of the supported locator types. It will also work with any other locator as long as you set it up in a merge locator using the fields from a locator below.
E.g. you could set up an AddressBase Basic locator in a merge locator, with no other locators present, and set up the schema to use the AddressBase DPA fields.
Below are the required fields for each locator type, you can set up your standardised schema using one set of these fields.

When using a merge or cascade locator with the Drilldown widget add it in using the corresponding locator type so that the fields match up correctly.
E.g. if you have set up your standardised schema to match the LLPG locator fields then when you use this with the Drilldown you would set it up to be an LLPG locator, using either the LLPGLocator class for a standard JavaScript application or setting the locator type to be “LLPG” when using it with the Web AppBuilder.
