Slider in <main> or <nav>?

Question

In Order to build a well-structured website with semantic HTML5 tags, is it better to put a slider (like this one: http://materializecss.com/media.html) inside the <nav> tag or does it rather belong to <main>?

Thanks! :)

Answer 1

In main
Nav for menu navigation only
