                                        while($row = mysqli_fetch_array($response)) {
                                    ?>
                                        <option value="<?php echo $row['id'];?>"><?php echo $row["brand"];?></option>
                                    <?php

                            <div class="form-group">
                                <label for="SUBPRODUCT">Sub Brand</label>
                                <select class="form-control" id="sub-brand-dropdown">
                                    <option value="">Select Sub Brand</option>
                                </select>
                            </div>
                        </form>
                    </div>
                </div>
            </div>
        </div>
    </div>
    <script>
    $(document).ready(function() {
        $('#brand-dropdown').on('change', function() {
            var brand_id = this.value;
            $.ajax({
                url: "get-subbrand.php",
                type: "POST",
                data: {
                    brand_id: brand_id
                },
                cache: false,
                success: function(response){
                    $("#sub-brand-dropdown").html(response);
                }
            });
        });
    });
    </script>
</body>
</html>

Step 5 : Fetch Sub Brand

get-subbrand.php

<?php
    include "config.php";
    $brand_id = $_POST["brand_id"];
    $response = mysqli_query($conn,"SELECT * FROM brands where sub_brand_id = $brand_id");
?>
<option value="">Select Sub Brand</option>
<?php
    while($row = mysqli_fetch_array($response)) {
?>
<option value="<?php echo $row["id"];?>"><?php echo $row["brand"];?></option>
<?php
    }
?>
