I am creating a plugin for Wordpress, using bootstrap 5.2.3.

I also look for a visual modification of the select box when using the 'multiple' attribute.

I have tried up to now these plugins, with no results: virtual-select bootstrap-multiselect select2 with select2-boostrap-5-theme css

Nowadays, is there any non-paid plugin that can modify the select box?

Thanks in advance for your help
