5. Press Save
6. Add a second Data Provider (for States/Regions)
   Name: States Regions Provider

    
    URL: http://localhost:8080/api/jsonws/region/get-regions/countryId/{countryId}
   

   User Name: [email protected]
   Password: adminuserpass
   Timeout: 3000
   Inputs Label: CountryId
   Inputs Parameter: countryId
   Inputs Type: Text
   Outputs Label: State Name
   Outputs Path: $..name
   Outputs Type: List

1. Press Save
2. Go to: Content and Data > Forms > Click + to create a new form
3. Add a 'Select From List' Field to the form
   Field Configuration
   Label: Country
   Create List: From Data Provider
   Choose a Data Provider: Countries of the World
   Choose an Output Parameter: Country Name
4. Press Save
5. Add another 'Select From List' Field to the form, this time dragging it over the previous 'Select From List' Field so they become grouped
   Field Configuration
   Label: States/Regions
   Create List: From Autofill
6. Press Save
7. Create a rule to provide the States/Regions for the country selected (see screenshot 03.)
   Click the Rules tab > Click +
   Configure Rule as per below:
   If [Country] [Is Not Empty]
   Do [Autofill] From Data Provider [States Regions Provider]
   CountryID [Country]
   State Name [States/Regions]
8. Press Save
9. Save and Publish the Form.
10. Open the Content Page for editing > Configure the Form widget to display the form > Press Publish
11. Go to the page
12. Select United States from the 'Country' list
    Note the States/Regions are populated in the second field list
13. Select Afghanistan as the Country

Expected Result
The regions of Afghanistan are populated if they are included in the data provider or alternately the States/Regions list shows as empty.

Actual Results
Though Afghanistan is selected as the country, the States/Regions remain those of the US.
