DataViews for Posts, Categories and Tags

[youknowriad]

Similarly to the pages, patterns and templates pages in the site editor, we should explore how we can leverage the same DataViews UIs, frame, editor, navigation... to power the Posts section of WP-Admin as part of the Admin redesign project.

There are a lot of challenges here:

• Reusing the "pages" dataviews without duplicating all the code.
• Reusing the site editor shell, navigation menus and routing logic
• Generating forms for categories and tags creation and modification without necessarily creating custom code DataViews: Forms #59745
• Extensibility DataViews: Extensibility #61084
• Backward compatibility
• Transition

There's a lot to cover and a lot of uncertainties, for these reasons, I'm proposing that we start a new experimental page in the Gutenberg plugin, where we explore a new page that could serve as a playground to explore these ideas and address all the blockers.

Task list:

• Bootstrap a site-editor like shell Bootstrap the dashboard layout #62409
• Add the "posts" dataviews page. (@ntsekouras)
• Add the "categories" dataviews page.
• Add the "tags" dataviews page.
• Leverage DataViews forms to implement "Add new category" and "Add new tag" (and edit forms as well)

Thank you for creating this and starting this work :)

I'm really excited about this one! As you mention there are many challenges / open questions. The main things for me are all focussed around what the rollout of the "Site Editor Frame" will mean to a lot of the other areas of the WordPress Admin.

Will this experimental posts screen display the old traditional WP left sidebar? Will it feature the admin bar? Admin notifications etc? Or will it replace the entire screen with the site editor like experience?

So essentially which of these three approaches are we going to take with this?

Table Only	Content Area Only	Entire Screen

Or will it replace the entire screen with the site editor like experience?

This is how I was going to experiment initially. I'm happy to iterate on these things though as the design settles. Would love to have some mockups to base the initial work on but I'm not too concerned.

I added some tasks to the issue for folks that want to help. Feel free to graph a task and give it a try.

I can try to do posts page for start.

Hi, I'm really interested in these DataViews-powered pages.

Would there be a way to hook into the edit URL/action for the objects? (For example, to offer a custom edit React-based experience rather than the Block Editor)

@dannyreaktiv Thanks for your interest. I think your use-case makes sense. I think it's fits more with the routing work / navigation customization and less about dataviews but it's definitely something that should be enabled. (Related issue #60584)
