Custom metadata for exhibits

We would like to add custom metadata fields to the “Add/edit Exhibit Page” for Exhibits.
Is this doable using a plugin hook or filter without modifying the plugin code?

Hello Andreas.
Maybe you could find some inspiration in this plugin: https://github.com/jaguillette/BlockParty
Hope this helps.

Nice plugin! But I’m mainly thinking about the “core” form fields for an exhibit (ie title, description etc) and any hooks or filters for adding additional input fields to that particular form on the add/edit page.
