I was looking to a solution whithin Indesign. So it is not possible?
InDesign CS6 or earlier is not designed for creating fixed layout EPUB files. Essentially it would have to be done in a very painful, very manual process. Anne-Marie Concepcion describes the process in this Lynda.com video:
The Rorohiko product is the best thing going at the moment.
Our first support for EPUB3 Fixed Layout is now available with the 2014 (June 18th) update to Creative Cloud.
Download the trial and let us know how we can improve it.
