Kindle does not support multi-level TOC in the ePub sense. A Kindle TOC is just another page in the book with hyperlinks to chapters/sections. Those hyperlinks can have an outline structure, i.e be 'multilevel' in appearance. But to use it, your reading position actually changes to the page with the TOC.

An ePub TOC is based on an NCX structure that is a separate component within the ebook, and the reading system can bring up a navigable TOC view, sometimes being able to 'collapse' the multi-level view. And you can dismiss the view without leaving your current position in the book. It is usually quite a bit nicer than what Kindle offers, but occasionally you find reading systems that only show the top level of the TOC (like Nook Touch). Probably that's what the OT is asking about.

Kindle ebooks often also contain an NCX, but it's only used for chapter navigation, and functionally it is really only top-level (though you can coerce it to navigating 2nd level also). The Kindle Previewer actually has an 'NCX view' that is very much the same as an ePub reading system. Wish they would add that to Kindle itself.
