I have created Custom Field of the type "Checkbox List" for a Custom Post Type "Talents", and also added some choices.
Now the editor is asking me, how to add more choices when she is working in a Talents post, or edit existing choices. Editors are not allowed to access any Meta Box items in the Dashboard.
How can I extend this Checkbox List field so that the Editor can edit existing choices and add new ones? I had tried to enable "Cloning", but then all previously added values/choices are not showing any more.
