Hi @kevin-mamaqi
Could you please explain what did you mean by “how to do it with select2?” If you want to show a taxonomy input field like the one on the backend, I believe you can use the acf_form() function. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/create-a-front-end-form/.
I hope this helps 🙂
