# Untitled test page

This page should not appear in the navigation.
Ensure pages with nav_exclude are ignored by navigation Pages with `nav_exclude: true` were included when sorting on `title` or `nav_order`. That could cause build failures when the type of value of the field differs from that on other pages, as reported in https://github.com/pmarsceill/just-the-docs/issues/406. Pages with `nav_exclude: true` or no `title` are never displayed in the navigation, so removing them from `pages_list` cannot break existing sites. This change also allows the removal of some tests in the code. (The indentation of the code should now be adjusted, but that has been deferred, to restrict the size of the diff for review.) For testing, the title of `404.html` has been changed to the number `404`, the page `docs/untitled-test.md` has been added, and `nav_sort_order` has been set to `case_sensitive`. Those updates give build failures with the current version of `_includes/nav.html`, but not after the suggested changes. It will still be possible for build failures to occur due to sorting fields of non-excluded pages with differing types of values (e.g., `nav_order`a mixture of numbers and strings). To make the code completely safe will require relatively complicated changes,. 2020-08-10 15:58:42 +02:00			`---`
