Select2 can take a regular select box like this...

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

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>.

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.

<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",

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.

// alter the remote JSON data

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

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