is it also possible to load entered data of a post type in a dropdown in gravity forms? This is a price list that is filled in at the back via meta box but must be reloaded at the front in gravity forms so that people can choose a price
Gravity Form can work with custom fields created by Meta Box as other regular fields of WordPress. But the field must have a value in the database to let GF look up in the column meta_key and meta_value (table wp_postmeta).
