Hi,

You can enqueue the select2 library then apply the function select2() to the selector with some Javascript code.

function enqueue_select2_jquery() {
    wp_register_style( 'select2css', 'https://cdnjs.cloudflare.com/ajax/libs/select2/3.4.8/select2.css', false, '1.0', 'all' );
    wp_register_script( 'select2', 'https://cdnjs.cloudflare.com/ajax/libs/select2/3.4.8/select2.js', array( 'jquery' ), '1.0', true );
    wp_enqueue_style( 'select2css' );
    wp_enqueue_script( 'select2' );
}
add_action( 'admin_enqueue_scripts', 'enqueue_select2_jquery' );

add_action( 'admin_footer', function() {
    ?>
    <script type="text/javascript">
        jQuery(document).ready(function($) {
            $('#field_id').select2();
        });
    </script>
    <?php
} );

Follow this topic for more information https://stackoverflow.com/questions/48879027/how-to-add-select2-js-in-wordpress-admin-side-theme-options.

And please notice, the plugin Meta Box also enqueues the library select2 when display some fields select (multiple => true), select_advanced ... so be careful when loading another select2 Javascript file might happen a conflict.
