This seems to work, we are using it for the admin area only.
add_action(‘acf/input/admin_footer’, function() {
if (!is_admin()) {
return;
}
?>
<script>
acf.add_filter(‘select2_args’, function(args) {
args.templateSelection = function(selection) {
var $selection = jQuery(‘<span class=”acf-selection”></span>’);
$selection.html(acf.escHtml(selection.text));
$selection.data(‘element’, selection.element);
return $selection;
}
return args;
});
</script>
<?php
});
