+To help fit your needs, this works with `<ul>`-based markup, as shown above, or with any arbitrary "roll your own" markup. Note that if you're using `<nav>`, you shouldn't add `role="tablist"` directly to it, as this would override the element's native role as a navigation landmark. Instead, switch to an alternative element (in the exammple below, a simple `<div>`) and wrap the `<nav>` around it.
