I'm adding dynamically a selected box items.

I want when I check a check-box set the value or the selected option of all the additional selected-box to the selected option of the first selected box.

So I'm using the following code to add dynamically input fields.

$(document).ready(function() {

  $("body").on("click", ".add_new_frm_field_btn", function() {

    var random = 1 + Math.floor(Math.random() * 1000); //generate random values..
    var index = $(".form_field_outer").find(".form_field_outer_row").length + 1;
    //added data-index and outer..class
    $(".form_field_outer").append(
      `<div class="col-12 outer" data-index="${index}_${random}">
            <div class="card-body form_field_outer_row"> 
            <div class="form-row">
                                        <div class="form-group col-md-2">
                                            <label for="inputState">Casting</label>
                                            <select  class="form-control maintCostField"  name="rows[${index}][id_casting]" id="id_casting" >
                                            <option selected>Choose...</option>
                                            @foreach($castings as $casting)
                                            <option data-id="{{$casting->id_casting}}" value="{{$casting->id_casting}}">{{$casting->nom.' '.$casting->prenom}}</option>
                                            @endforeach
                                            </select>
                                        </div>
                                        <div class="card-body ">
                                            <button type="button" class="btn btn-outline-warning mb-1 remove_node_btn_frm_field">Delete</button>
                                        </div>
                                        
                                    </div> </div></div> `);


    $(".form_field_outer").find(".remove_node_btn_frm_field:not(:first)").prop("disabled", false);
    $(".form_field_outer").find(".remove_node_btn_frm_field").first().prop("disabled", true);
  });

          </div>
        </div>
      </div>
    </div>

  </div>

</div>

I want when I Add a multiple additional selected-box and I check the checked box all the additional selected-box get the same selected option of the first selected-box.

That means when I add the first row and I select option1 , all the additional rows should get the option1 as the first additional row.

I'm still a beginner in jQuery and JavaScript, is it possible to do this and is it possible to do it with jQuery or JavaScript?

First you need to set unique id for each select item: id="id_casting${index}".

Then you set selected option if your check box has checked:

var checked = $("#checkAll").is(':checked')
if (checked)
     $("#id_casting" + index).val($("#id_casting").find(":selected").val());


        $(document).ready(function () {

            $("body").on("click", ".add_new_frm_field_btn", function () {
               
                var random = 1 + Math.floor(Math.random() * 1000); //generate random values..
                var index = $(".form_field_outer").find(".form_field_outer_row").length + 1;
                //added data-index and outer..class
                $(".form_field_outer").append(
                    `<div class="col-12 outer" data-index="${index}_${random}">
            <div class="card-body form_field_outer_row">
            <div class="form-row">
                                        <div class="form-group col-md-2">
                                            <label for="inputState">Casting</label>
                                            <select  class="form-control maintCostField"  name="rows[${index}][id_casting]" id="id_casting${index}" >
                                            <option selected>Choose...</option>
                                            @foreach($castings as $casting)
                                            <option data-id="{{$casting->id_casting}}" value="{{$casting->id_casting}}">{{$casting->nom.' '.$casting->prenom}}</option>
                                            @endforeach
                                            </select>
                                        </div>
                                        <div class="card-body ">
                                            <button type="button" class="btn btn-outline-warning mb-1 remove_node_btn_frm_field">Delete</button>
