  • You could use a relationship field instead. A post object field that allows multiple values is just another way of displaying a relationship field.

    Or you can create an acf/validate_value filter $value in this case will be an array of post IDs and you can do

    if (count($value) > $my_max_posts) {
      $valid = 'No more than '.$my_max_posts.' allowed';

    I’d also add a note to the field instructions about the maximum.

    You could probably also do this using javascript and the select2_init hook to alter the select2 settings
