How to load data in dropdown menu in Laravel?

I have dropdown menu in template Laravel.

This is select list with names of countries.

I need to load cities in the closest dropdown menu after clicking by item of country.

So, I think it should be Ajax request to controller Laravel, that to get cities by id country.

Maybe there is any solution?

You could do something like this in jQuery

<select class="country">
     <option>Select</option>
     <option value="usa">United States</option>
     <option value="india">India</option>
     <option value="uk">United Kingdom</option>
</select>
<input type="hidden" name="_token" value="{{ csrf_token() }}">

<div id="response"></div>

The javascript, don't forget to put it inside $(document).ready()

$("select.country").change(function(){
   var selectedCountry = $(".country option:selected").val();

   $.ajaxSetup({
        headers: {
             'X-CSRF-TOKEN': '{{csrf_token()}}'
        }
   });

   $.ajax({
        method: "POST",
        url: "countriesList",
        data: { country : selectedCountry }
        }).done(function(data){
             $("#response").html(data);
        });
 });

And then in your Laravel Controller or directly from the route, you could return the countries and cities as multi-dimensional arrays

Route::post('countriesList', function() {
    if(Request::ajax()) {
        $country = Input::get('country');

        $countryArr = [
            "usa" => ["New York", "Los Angeles", "California"],
            "india" => ["Mumbai", "New Delhi", "Bangalore"],
            "uk" => ["London", "Manchester", "Liverpool"]
        ];

        if($country !== 'Select'){
            echo "<label>City:</label>";
            echo "<select>";
            foreach($countryArr[$country] as $value){
                echo "<option>". $value . "</option>";
            }
            echo "</select>";
        }
    }
});
