// Check/uncheck all checkbox choices

(function() {
  'use strict';

  var CHECKALL = 'check_all'; // Field code of checkbox to check/uncheck all checkboxes
  var CHECKBOX = 'mycheckbox'; // Field code of checkbox to have all choices checked/unchecked

  var events = ['app.record.create.change.' + CHECKALL, 'app.record.edit.change.' + CHECKALL];

  kintone.events.on(events, function(event) {
    var record = event.record;
    var changes = event.changes.field.value;

    if (changes[0] === 'check all') {
      record[CHECKBOX].value = ['sample1', 'sample2', 'sample3', 'sample4', 'sample5'];
    } else {
      record[CHECKBOX].value = [];
    }
    return event;
