Using a custom Walker, the start_el() method has access to $depth param: when it is 0 the elemnt is a top one, and we can use this info to maintain an internal counter. When the counter reach a limit, we can use DOMDocument to get from full HTML output just the last element added, wrap … Read more
Use a custom walker, remove anything you don’t need and add your classes. Here is a walker I use to get a list with clean markup: T5_Nav_Menu_Walker_Simple. Your could also filter ‘nav_menu_css_class’ or ‘wp_nav_menu_items’. But a walker class is easier to understand and to control in my opinion.
You can’t just pass the string “parent” to get_categories.

Your best bet is to use a combination of JS waypoint libraries with the WP Rest API. When element is visible, fetch content and display. Pretty simple. Instead of the <nextpage> you could also wrap this in a custom shortcode but this is primarily a JS problem, not really a WP issue.
Are you sure that you have placed the files in the same directory? I’ve tested the code that you have provided and it’s working. However, you could try this out (a different way of giving sections an id): If you have done this, just use the same way of linking:
