WPPizza – A Restaurant Plugin for WordPress › Support › Faq’s WPPizza v2.x (read only)(for WPPizza FAQ’s v3.x go here) › sorting menu items
just use the order attribute (which btw is also available in quick edit).
if you cannot see it in individual posts/menu items, you might have to click on “screen options” and check “attributes” first
there are also a variety of drag and drop (custom) post type plugins available on wordpress if you prefer to sort the order that way
alternatively – as of version 126.96.36.199 – you can sort items by id, title or date , overriding the default sort order (wppizza->layout => Menu items sort order (in category):)
