Multiple pages with the same title but different parents not differentiated in link editor dialog

[jdgrimes]

Linking to another page/post on the site is made easy by the link editor dialog, which displays a list of matching items. The type of post each item is is shown on the right, so it is easy to tell the difference between multiple items with the same name if they are different post types. However, sometimes with hierarchical post types like pages there are multiple items with the same title, but different parents. There is no way to tell them apart. (See attached image.) It would be helpful if in this case the parent of the page was also shown.

Example of this issue

+1 for this.

A couple of possible permutations for posts with a parent. First, we could show as breadcrumbs in the link dialogue like so:
Parent-1>Events
Parent-2>Events

or, we could create a center column that listed the parent of a page:
Events | Parent: Parent-1 | Page
Events | Parent: Parent-2 | Page

Other ideas?

Looking at 39607.diff: can we do something like:

$parent_id = wp_get_post_parent_id( $post->ID );

if ( $parent_id ) {
   ....
}

Seems more readable.

Also, not sure the parent title should be after the post title. Doesn't seem logical and is the opposite in the permalink.

Also, what do we do for grandparents, great-grandparents, etc. Should we skip them? Perhaps go to three levels deep?

In any case, needs some feedback on how to display:

Paten title / Post title
Grandparent title / Parent title / Post title

(Separating them with slashes seems good as it resembles the URL structure.)

Replying to azaozz:

I as originally thinking that the parent title would be after, because the part you are searching for should come first. What if the title(s) are long and the end has to be cut off? (I'm not sure how that is handled here.) The parent title should probably be clipped, not the child.

Also, what do we do for grandparents, great-grandparents, etc. Should we skip them? Perhaps go to three levels deep?

Originally I had thought that the parent would only need to be shown when multiple items shared the same title. If we did that, then I guess it would only make sense to show the grandparents if the parents were also the same. But perhaps it is better to always show the parents, maybe there are other times that is helpful, even when titles don't match exactly??

In any case, needs some feedback on how to display:

Assuming that the parent was shown second, I was thinking something along the lines of:

Child title < Parent Title

I envisioned that the parent title would be in a slightly lighter/less bold color than the child title, so as not to distract from the child so much. That would probably be especially good if the parent is always shown for every item, and not just for ambiguous ones.

Closing this as wontfix as the classic editor is in "maintenance mode" meaning we're not accepting enhancements.

That said, I think this functionality would be useful to have in the block editor. I'd encourage any interested contributors to open an issue or PR in the Gutenberg repo.
