It’s easy to use adjacent or previous – next single post navigation when you want WordPress posts sorted by publish date. But often you need to sort posts or custom post types by title alphabetically or by menu order (using page attributes). I’ve always found this difficult, and while there are plugins that should help with WordPress menu order sort, you may still need to edit or create new templates to get it to work.
A workaround, of course, is just to change the publish date of the posts, so that they’re in the correct order, but that’s not always best, so here’s a method to use WordPress menu order for adjacent previous-next single post navigation. So you can just add the code to your child theme functions.php and then add the styles to your style.css. The sort functions work for any WordPress theme, but since I use Genesis Framework, that’s what I used to add the navigation.
