Title: Added the support for <menu> elements for the Tab component.

In some applications, with the regard of HTML semantic quality, some may use the `` elements of type "list" (``) instead of the classic `

` elements. The JavaScript for the Tab component currently doesn't know how to handle as it only expects for `

` elements.

This PR will use the `` elements as a backup only when `

` elements aren't found.
