Ordering pages (menu, select meals, cart, checkout, account) are generated by Sprwt's ordering modules and are not CMS pages – you configure them under Settings (the Theme: … and Order: … tabs) rather than in Pages. CMS pages are your marketing/content pages (the home page when the site's theme is set to use a page, about, FAQ, contact, landing pages, legal pages, blog). You can, however, place ordering widgets inside CMS pages with modules such as Current Menu – Slider, Ordering Modules, Packs, Subscriptions Groups, Single Meal or Zipcodes Search to build custom landing pages that lead into the order flow.
