Too much redundant information displayed in links between versions on api.drupal.org

I feel like after doing the branch clean up and also changing the styling of the element, this doesn't seem like a big issue:

Though I agree that maybe it's a lot of information not really needed, as it is same name and namespace already).
Maybe something like this feels "cleaner"?

I would use a select form element like in the first screenshot on comment #5 and as the issue summary suggests. It should be clear it takes to the same page, but for a different Drupal version.

Now that the fieldset has been changed to Same name in other branches, this is probably no longer needed.

Same name in other branches means the namespace could be different, even if the class name is the same. For example, for the Block class, some of the classes given in that fieldset are the following.

• core/modules/views/src/Plugin/views/display/Block.php \Drupal\views\Plugin\views\display\Block
• core/modules/block/src/Entity/Block.php \Drupal\block\Entity\Block
• core/lib/Drupal/Core/Block/Annotation/Block.php \Drupal\Core\Block\Annotation\Block

The only repeated parts are core/ in the path and \Drupal\ in the namespace, which I would rather show in that list.

It is still possible to show less redundant information if the information would be grouped by filename.

• core/modules/views/src/Plugin/views/display/Block.php \Drupal\views\Plugin\views\display\Block
  • Link for Drupal 10
  • Link for Drupal 9
  • Link for Drupal 8
• core/modules/block/src/Plugin/migrate/source/Block.php \Drupal\block\Plugin\migrate\source\Block
• Link for Drupal 10
• Link for Drupal 9
• Link for Drupal 8

As the link texts should be preferably different from Link for Drupal 10, some redundant information would still be shown. I am not sure it is worth changing how those links are rendered.

That grouping by namespace/filename looks good, but agree that there would still be some repetition.
It's all controlled here: https://git.drupalcode.org/project/api/-/blob/2.x/src/Formatter.php?ref_...

Maybe we can even put all links in 1 row?

ie:

• core/modules/views/src/Plugin/views/display/Block.php \Drupal\views\Plugin\views\display\Block
  • [Drupal 10] [Drupal 9] [Drupal 8]
• core/modules/block/src/Plugin/migrate/source/Block.php \Drupal\block\Plugin\migrate\source\Block
  • [Drupal 10] [Drupal 9] [Drupal 8]

Where [something] represents a link.

Using Drupal X as link text, those links could be placed on a single line. Even if the text would be Drupal 9999, there should not be any problem. 👍🏻

📌 Add 'supported' flag to branches to use to direct users and bots Active that is already committed and will be deployed later this week help a lot with this IMHO, although not directly implementing this per say.
