                    var $selectDropdown = $("#select_1").empty().html(' ');

                    $.each(data, function(i, val){                      
                        $selectDropdown.append($("<option></option>").attr("value",val.id).text(val.name));

                    })

                    $selectDropdown.trigger('contentChanged');
                    $('select').on('contentChanged', function() {
                      // re-initialize (update)
                      $(this).material_select();
                    });
                },
                error: function (xhr, status, err) {
                    // console.log(xhr);
                    // console.log(status);
                    // console.log(err);
                },
            });
        }

            get_selected();         
        })

 $(document).ready(function() {
    $('select').material_select();
 });
 
 $(document).on('change','#select_1', function(){
     get_selected();         
})


function get_selected(){
     var data=[{id:1,name:"ABC"},{id:2,name:"XYZ"},{id:3,name:"PQR"}];
     
     var Options="";
    $.each(data, function(i, val){ 
      Options=Options+"<option value='"+val.id+"'>"+val.name+"</option>";
  });
  $('#select_2').empty();
  $('#select_2').append(Options);
  $("#select_2").material_select()
}
