I already applied a custom order for that toplevel navigation of my page, however it does not instantly sort the submenus alphabetically, although i believed this behavior:
Pages are usually ordered alphabetically, but you can put a number above to change the order pages appear in. (We know this is a little janky, it’ll be better in future releases.)
I implemented the navigation by using this type of code:
<?php wp_page_menu( 'sort_column=menu_order' ); ?>
Finally, will i need to go and by hand order my static pages, or must i by hand program an order from the menu products?
I believe the My Page Order extension may be what you're searching for.
Also, perhaps you have attempted:
rather than 'menu_order'?
Per the Codex, it appears such as the title would lead to alphabetical sorting?
