How to add a link in the menu that scrolls to a page section (Anchor)

See video here:

- Add a new menu item in your menu: Go to WP-Admin > Appearance > Menus.

- Create a new 'Custom Links'. In the 'url' field, add "/#" and your Anchor ID you previously set. So if your anchor is about, the url will be /#about

* If you need to point to an anchor which is on another page than your homepage, then you need to add the slug name in the url. Eg: /bio/#about
