Hi. This may either be a stupid question or something that isn't possible. I have a client who wants a front end form, where people can submit a list of credits, each of which can be categorized as either 'film', 'television', 'commercial', etc. All of this is registered as a custom post type. I have setup some other fields with a custom meta box, however I am not sure if its possible to have a list of custom fields for each credit, and also the ability to choose a category for each field from a predefined dropdown list. Any help would be greatly appreciated!
