This Extra Field Type is available in Profile Builder Basic, Pro, or Agency.
You can use this extra field type to allow users choose a Custom Post Type (Page, Post or Custom Post Type).
You can specify the field title, meta-name to be stored in the database, description, default option and show post type (post, page or cpt).
Also, you can set whether this field should be required or not.
This is how it looks like in the front-end.
