For me it's work with that : Yoopies@4bb320e
But I don't know if there's something else to add or if I can do a PR

The attributes block in Yoopies/bootstrap-bundle@4bb320e is unnecessary since the twig uses form_div_layout.html.twig which already has that block anyway. All that needs to be changed are those two lines inside choice_widget_options and then choice_attr works perfectly.
