Hi there !

I purchased a Kobo libra 2 and have issue creating a nested table of content.
This seems to be a common issue for books with lots of chapters such as the Bible.

This messages points to the kobo spec file that tells it should work for ebook v3

The document in itself gives details about how the nav should be done:
https://github.com/kobolabs/epub-spe...f-contents-toc
More details in:
https://www.w3.org/publishing/epub3/...ec-package-nav

I try to follow those doc and ended up with something like this:

<nav epub:type="toc" id="toc">
<h1>Table of Contents</h1>
 <ol>
      <li><a href="01-TOC.xhtml">Table Of Contents</a></li>
      <li><a href="02-Foreword.xhtml">Foreword</a></li>
      <li>
          <a href="03-Gen.xhtml">Genesis</a>
                 <ol>
                 <li><a href="03-Gen-001.xhtml">1</a></li>
                 <li><a href="03-Gen-002.xhtml">2</a></li>
                 …
                </ol>
      </li>
         …
 </ol>
</nav>

It display as intended in Sigil, but on the actual kobo device, the table of content is still flat.

The actual file validate and is available here:

Any idea If I am doing something wrong or if the kobo is not able to display embedded list other than as a flat list ?
