Choices.js 输入框标签下拉个性化多选插件

一个普通的、轻量级的（~20kb gzipped）、可配置的选择框/文本输入插件。与 Select2 和 Selectize 类似，但没有 jQuery 依赖项。

使用实例：

  // Pass single element
  const element = document.querySelector('.js-choice');
  const choices = new Choices(element);

  // Pass reference
  const choices = new Choices('[data-trigger]');
  const choices = new Choices('.js-choice');

  // Pass jQuery element
  const choices = new Choices($('.js-choice')[0]);

  // Passing options (with default options)
  const choices = new Choices(element, {
    silent: false,
    items: [],
    choices: [],

    maxItemCount: -1,
