This snippet could come really handy for several reasons. When you’ll need to do advanced customization of the checkout and its fields, hopefully you’ll thank me then 🙂
In today’s snippet, we will add a new checkbox and another new “hidden” field – then, if the checkbox is ticked, the field will show, otherwise it will disappear again.
