;(function($, window, document, undefined){

  var buttonNextLevelHtml = '<span class="arrow js-arrow">&rsaquo;</span>',
    buttonPrevLevelHtml = '<li class="back js-back">Назад</li>',
    toggle = $('.js-toggle'),
    overlay = $('.overlay'),
    body = $('body'),
    menu = $('.multilevelMenu'),
    link = menu.find('a'),
    menuList = menu.find('li').find('ul');

  //create animate-menu function
  function openMenu() {
    body.toggleClass('fixed');
    setTimeout(function() { $('.close-list').removeClass('close-list') }, 400);
  };

  //animate menu function Call
  toggle.add(overlay).on("click", function(){
    openMenu();
  });
  //the end animate menu function Call

  //add switch-button for children ul
  link.append(function(indx, val){
      var out = '';
      if($(this).parent('li').find('ul').length != 0) {
        out = buttonNextLevelHtml;
      }
      return out
    });

  //add back-button
  menuList.prepend(buttonPrevLevelHtml)

  //var block-two
  var buttonNextLevel = $('.js-arrow'),
      buttonPrevLevel = $('.js-back');

  //view next level menu
  $(link).on("click", ".js-arrow", function(e){
    e.preventDefault();
    e.stopPropagation();
    $(this).parents('ul').addClass('close-list');
    $(this).closest('li').children('ul').addClass('active-menu');
  });



  //view prev level menu to click "back"
  buttonPrevLevel.on("click", function(e){
    $(this).closest('ul.close-list').removeClass('close-list');
    var self = this;

    setTimeout(function() {
      console.log($(self).closest('ul'));
      $(self).closest('ul').removeClass();
    }, 400);

    if($(this).parent().parent().parent().parent().hasClass('multilevelMenu')) {
        $('.menuSearch').removeClass('none');
    };

  });

  //Hidden search-block
    buttonNextLevel.on("click", function(){

    })

})(jQuery, window, document);
