I can able to invoke the method when submit the button.But I need to invoke method when drop down value selected from drop down list in SpringBoot.

I tried using below but didn't worked.

Please find the sample code as shown below:

<select th:field="*{country}" xmlns:th="th">
   <option value="">Select</option>
   <option value="first">1</option>
   <option value="second">2</option>
   <option value="third">3</option>
</select>

Java code:

@Controller
public class Countries() {

  @GetMapping(value = "/")
    public String menu(ModelMap model) {

        model.addAttribute("createMenu", new Country());

        return "menu";
    }

  @RequestMapping("/first")
    public List<Object> country(){

        System.out.println("first");

        return null;

    }
 }

When selected dropdown value then invoke method to get list of states.Can anyone please help me on this.
