phonecatApp.controller('myController', function myController($scope, $http) {
  $http.get('https://api.zotero.org/users/475425/collections/9KH9TNSJ/items?format=json')
    .then(function(response) {
      var data = response.data

      data = data.filter(function(obj) {
          return true
        })
        .map(function(obj) {
          return {
            key: obj.key,
            parentItem: obj.data.parentItem,
            title: obj.data.title
          }
        })
      console.log(data)

      $scope.getParentData = function() {
        var log = []

        angular.forEach(data, function(value, key) {
          if (value.parentItem === undefined) {
            this.push(value)
          }
        }, log)
        return log
        console.log(log)
      }

      $scope.getChilds = function(p) {
        var log = []

        angular.forEach(data, function(value, key) {
          if (!value.parentItem || value.parentItem !== p.key) {
            return
