In the soon to be released 8.1 version you can use the following filters to add new meta data types:
cn_family_relation_options cn_address_options cn_phone_options cn_social_network_options cn_instant_messenger_options cn_email_options cn_link_options cn_date_options
If a new type is added and later removed, there is no code to handle the display of the missing type.
Even though there is a filter for
cn_social_network_options it is almost useless because any newly added types will not have icons unless they are added to the plugin’s icons folder.
This is a first step. What I really need to do is add “registration” helper functions that hook into these filters to make it easier to deal with from a dev standpoint.
Any way, this should be enough to let you do what you want to do.
