I have a custom post type and taxonomy so the user can post in a specific areas in the theme. User (admin) can add categories easily. But the categories that has been added through my taxonomy don't show up in wordpress regular posts category option.
I do not have any problem with displaying those posts on theme. My problem is to showing those custom categories in regular post's category option.
Is there a way to make ;
a custom category created by taxonomy to be shown in wordpress regular post's category section?
