I recently tried creating a navigational TOC in Indesign CC. I followed the tutorial and it worked. I tried it again with a new document, I saved the TOC style in the TOC dialogue window. When I exported as epub, I went to select the file name for navigation TOC, but my TOC style does not appear. Does anyone know why it didn't work? I tried the fixed epub file. If I try multilevel TOC, my navigation menu does not display correctly. Thanks.
