Have produced a custom navigation menu in wordpress with a pages plus some groups inside it as links. Now after i load recption menus using default options I've two problems:

1) the groups without any posts inside them aren't turning up - How you can disable this behavior? 2) the web pages are turning up alphabetically around the menu - how you can place them correctly?

Once the page calls wp_list_categories() you need to pass the argument &hide_empty=0.

I needed to make use of this for my website. A little of Searching informs you more.
