How to show just specific cfid range?

[NimaNowroozi]

Is there any way to just show the specific cfid range in epub js? I want to avoid user to see other contents which is inside the epub, and limit them to a specific range of cfid.

There is no such method and even if there was, I would not count on it.

The best way would be to build a script that will cut the actual EPUB and create a smaller file.

We did similar thing for demo books.
