Advanced Custom Fields natively handles front-end forms, but multi-steps forms are not supported out of the box.
This proof-of-concept has been created in order to explain how to use multiple ACF fields groups to display a multi-steps front-end form.
Head to the class-shortcode.php file to discover the main logic behind this. This is the main file in charge of outputting our [acf_multiforms_example] shortcode and doing the necessary magic when processing the form with acf/save_post.
It is heavily documented to explain how things work.
The form displayed below uses an enhanced version of acf_form(); it has a total of 3 steps.
The first step is composed of two ACF fields groups, while the two other steps display only one single field group each.

Nothing new here actually :)
In the back-office, ACF acf_form() takes care of saving form data in the proper post meta fields.
Notice that the first two metaboxes below are the ones displayed in the first step of the front-end form.
