        Select2 also supports multi-value select boxes. The select below is declared with the <code>multiple</code> attribute.

        A placeholder value can be defined and will be displayed until a selection is made.

        <select class="js-example-placeholder-single js-states form-control">
          <option></option>
        </select>
      </p>

      <p>
        Select2 uses the <code>placeholder</code> attribute on multiple select
        boxes, which requires IE 10+. You can support it in older versions with
        <a href="https://jamesallardice.github.io/Placeholders.js/">the Placeholders.js polyfill</a>.

      <p>
        Select2 provides a way to load the data from a local array.

      <p>
        <select class="js-example-data-array form-control"></select>
      </p>

      <p>
        You can provide initial selections with array data by providing the
        option tag for the selected values, similar to how it would be done for
        a standard select.
      </p>

      <p>
        <select class="js-example-data-array-selected form-control">
          <option value="2" selected="selected">duplicate</option>

  <section id="data-ajax" class="row">
    <div class="col-md-12">
      <h1>Loading remote data</h1>

      <p>
        Select2 comes with AJAX support built in, using jQuery's AJAX methods.
        In this example, we can search for repositories using GitHub's API.
      </p>

      <p>
        <select class="js-example-data-ajax form-control">
          <option value="select2/select2" selected="selected">select2/select2</option>
        </select>
      </p>

      <p>
        When using Select2 with remote data, the HTML required for the
        <code>select</code> is the same as any other Select2. If you need to
        provide default selections, you just need to include an
        <code>option</code> for each selection that contains the value and text
        that should be displayed.
      </p>

      <pre data-fill-from=".js-code-data-ajax-html"></pre>

      <p>
        You can configure how Select2 searches for remote data using the
        <code>ajax</code> option. More information on the individual options
        that Select2 handles can be found in the
        <a href="options.html#ajax">options documentation for <code>ajax</code></a>.
      </p>

      <pre data-fill-from=".js-code-data-ajax"></pre>

      <p>
        Select2 will pass any options in the <code>ajax</code> object to
        jQuery's <code>$.ajax</code> function, or the <code>transport</code>
        function you specify.
      </p>

<script type="text/x-example-code" class="js-code-data-ajax">
$(".js-data-example-ajax").select2({
  ajax: {
    url: "https://api.github.com/search/repositories",

    delay: 250,
    data: function (params) {
      return {
        q: params.term, // search term
        page: params.page
      };
    },
    processResults: function (data, page) {
      // parse the results into the format expected by Select2.
      // since we are using custom formatting functions we do not need to
      // alter the remote JSON data
      return data.items;
    },
    cache: true
  },

  templateResult: formatRepo, // omitted for brevity, see the source of this page

  <section id="disabled" class="row">

        Select2 will response the <code>disabled</code> attribute on

        with <code>disabled: true</code> to get the same effect.

        and from remote sources, where the object has
        <code>disabled: true</code> set.
