@rovenann:
I experimented with converting top-level pages on my site to Block format and updating those pages and didn’t see any improvement in my case. I’m glad it seemed to work for you.

As a side-note, the process of using Gutenberg blocks to convert my Classic pages required extensive HTML knowledge to reproduce the same layout and look. I had to manually add <a href=""</a> to turn images into links; title="" to add tool tips; and my own classes for styling. All of my custom code was deleted when I made the conversion, requiring me to re-do all of it. Gutenberg has made WordPress exponentially more difficult for those who use custom HTML/CSS on their sites.

Marius L. J. (@clorith):
After reading the posts you linked to at github (https://github.com/WordPress/gutenberg/issues/9441) my takeaway is:

1) WP Users who have large websites with multiple hundreds of pages are small in number and;
2) Gutenberg developers do not find the issue which is the subject of this thread a priority because it affects only a small percentage of Users.

My conclusion is that those who have large websites generally choose not to use WordPress and that WordPress perpetuates this dynamic by not prioritizing the issues that this group of Users is experiencing. Update after Gutenberg update comes and goes with no solution to the Parent Attribute drop-down content deficiencies discussed here. I truly feel bad for those WP Users who do not have HTML/CSS skills.

Well said @jmavilaroman. Put another way: The subject of this thread is not “whether” the parent attribute drop-down appears but, rather, the “content” of the drop-down once it does appear.

Thanks, Marius, for the update.

Someone pointed out that the Parent Attribute in Gutenberg works in Quick Edit mode. When I’m building a page with needed Gutenberg features I navigate to Quick Edit, set the correct parent page, then navigate back to the Edit Page (I usually have multiple browsers open to make it as painless as possible). For simple pages I just use the Classic Editor plugin. It would be nice if a Gutenberg developer would chime in and shed some light as to why this issue is lingering on for so long.

It seems that the only pages that show in the Parent Page drop-down are those that were created with WP 4.xxx. None of the pages I created with WP 5+ are listed. Also, my UI’s Parent Page drop-down shows multiple instances of the pages and their children. In some cases I have a parent page with up to 30 or more child pages (photography website with a main gallery page and individual sub-pages for each image in the gallery). So the parent attribute drop-down displays hundreds of pages and sub-pages, multiple repeats of those pages, and only those pages that were created pre-WP 5. I just don’t get why the code from the Classic Editor plugin isn’t just used in Gutenberg. The Classic Editor plugin works perfectly, which is why I am still using it…

Unfortunately the Gutenberg plugin also has the issue with the incomplete page list in the parent attribute selection dialog box. Exiting Page Edit and going to Quick Edit to choose the parent page is inconvenient, but a doable workaround until the issue is corrected. Since I don’t have any other major issues with the core Gutenberg, I will use that instead of the plugin to save resources. Hopefully the Gutenberg Team will be ready with something soon…

Hi Joy. Thank you for your quick and informative response. I will install the Gutenberg plugin for its latest bug fixes (great tip!). I would rather move forward with Gutenberg than stay behind with the Classic Editor.

Hi everyone,

Ditto for me with this issue. Some parent pages do not show up in the Page
Attributes–>Parent Page list. What happens most often is that I create a new page and publish it. I then create another new page that needs to be the first new page’s child, but that first new page doesn’t show up in the Parent Page list, grinding my work to a halt. I just updated to WP 5.1.1 hoping this issue had been resolved, but no such luck. Sooo–back to the Classic Editor plugin.
