I have an html module that needs to go between the variant selector and the add to cart button. Any ideas?
Yes, 1st google this “wordpress action after variation” you’ll find a SE ppost from 11 years ago with the answer
So the action you need is woocommerce_before_add_to_cart_button and an example might be
add_action( 'woocommerce_before_add_to_cart_button', function () {
echo do_shortcode( '[fl_builder_insert_layout id=5705]' );
});
Where 5705 would be the ID of your saved HTML module.
