                            ssubmenu = dataMenu.SubMenus;
                            var splittingSsub = [];

                            splittingSsub = ssubmenu.split(',');
                            alert(splittingSsub.toString());
                            alert('3');

                                alert(stringBuilder.toString());
                                alert(4);
                            }
                            stringBuilder.push('</ul></div>');
                            alert('5');
                        }
                        alert('endloop');
                        stringBuilder.push('</li>');

                    }
                    stringBuilder.push('</ul></div>');


                }

                stringBuilder.push('</li>');

                $(".menu").append(stringBuilder.join(''));
            });
        }
    });
