  <section id="basic" class="row">
    <div class="col-md-4">
      <h1>The basics</h1>

      <p>
        Select2 can take a regular select box like this...
      </p>

      <p>
        <select class="js-states form-control"></select>
      </p>

      <p>
        and turn it into this...
      </p>

      <p>
        <select class="js-example-basic-single js-states form-control"></select>
      </p>
    </div>

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

      <h1>Multiple select boxes</h1>

      <p>
        <select class="js-states" multiple="multiple"></select>
      </p>

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

      <p>
        <select class="js-example-basic-multiple js-states form-control" multiple="multiple"></select>
      </p>
    </div>
    <div class="col-md-8">

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

<script type="text/x-example-code" class="js-code-multiple">
$(".js-example-basic-multiple").select2();
</script>
    </div>
  </section>

  <section id="placeholders" class="row">
    <div class="col-md-4">
      <h1>Placeholders</h1>

      <p>
        A placeholder value can be defined and will be displayed until a selection is made.
      </p>

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

      <p>
        This works for multiple select boxes as well.
      </p>

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

  <section id="data-array" class="row">
    <div class="col-md-4">
      <h1>Loading array data</h1>

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

      <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>
        Select2 comes with AJAX support built in, using jQuery's AJAX methods.

        <select class="js-example-data-ajax form-control"></select>
      </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.

        Select2 will correctly handled disabled results, both with data coming
        from a standard select (when the <code>disabled</code> attribute is set)
        and from remote sources, where the object has
        <code>disabled: true</code> set.
      </p>
