Is there a way to add a meta box to the page edit screen on the fly?
What I am trying to do is create a few custom content boxes underneath the main content box on the page edit screen. I don’t know how many of these boxes are going to be needed, and I would rather not display a load of them for only one to be filled out on one page and five on another.
So I would like to add them on the fly. As and when needed, however many there may be needed.
Is this possible to do? And if so, how?
All answers will be gratefully received.
