                              <div class="form-group">
                                <label class="sr-only" for="form-last-name">Address</label>
                                <textarea rows="4" style="height:100px;" name="address" placeholder="Address..." class="form-last-name form-control" id="form-last-name"></textarea>
                              </div>
                                    <button type="submit" class="btn">Submit</button>
                                {!! Form::close() !!}

How do I do it in Laravel?
