Is it possible to add to a custom field which is within a custom post type?
I have a form which shows custom fields created in the usual way, but if I have custom fields within specific custom post types, it does not show them in the drop-down when trying to select an existing custom field.
You don't have to use the drop down to select the custom field name, if it isn't showing up because it's in a custom post type OR it has an underscore in front of it then just select "New" and type in the name of the custom field. It doesn't matter if it exists or not, selecting New will let you manually type in the name.
