Overrides in Sync Patterns: expand block support

[liviopv]

What problem does this address?

Users should be able to overrides more blocks that are can hold actual content, not just Paragraph/Heading/Image/Button

What is your proposed solution?

Some ideas:

• List Block > List Items
• Quote Block: citation
• Gallery > Image
• Verse
• Preformatted
• File
• Video
• Embed (and variations)
• Nested blocks inside: Group, Cover, Column, Media & Text

@SantosGuillamot, that’s also related to Block Bindings.

[SantosGuillamot]

The idea is to add support for more blocks progressively to ensure everything works as expected. It's great to know which ones feel more important to have that in mind.

Should we also add "custom blocks" to the list here? As a developer I would love to be able to expose the block connections / pattern overrides feature in custom blocks I need to build.

[SantosGuillamot]

Yes, custom blocks are also part of the roadmap, although it will probably take more time. They depend on the HTML API supporting any HTML tag and they will need a proper opt-in mechanism. I've added it to the block bindings API epic.

From the list above the Verse and Preformatted blocks should be close in implementation to the Paragraph and Heading block so if someone would like to give it a try, @SantosGuillamot and I can help with reviews.

The Group block would be a great way to provide an open area for inner-blocks.

@dannyreaktiv you'll dig this issue on that exact topic: #61225

Wow. Thank you!

I believe the Block Binding support for the Embed block can be useful.

Is this the best place to suggest it, or is there a dedicated thread?

[SantosGuillamot]

I believe we can use this same conversation to gather feedback on the most important blocks 🙂

Overrides for the Cover Block Image: #63763

Because of this limitation and the way the Details block is built, there's also no way for someone to use this feature in a reusable block.

A major use case is the attached image where I'm building a page of dozens of speaker bios on a page that are collapsed by default so the page isn't overwhelming.

Aside: Maybe this ship has sailed, but if the

block was treated more like a Group block wouldn't this enable someone to edit the first text as a heading or paragraph instead? (and thus the "group" could be the reusable block and all the content would be editable separately. I see now it currently outputs that first bit of text as

although it styles it the same as normal paragraph text.

@fabiankaegy created a related issue explaining how we could open support for custom blocks that are rendered dynamically with render_callback on the server:

• Open up "Pattern Overrides" and therefore intern block bindings to custom dynamic blocks #64870

More ideas to core blocks that act like containers:

• Idea: using the group block in synced patterns as a freeform content area (via pattern overrides) #61225
• Overrides in Synced Patterns: allow enabling overrides in parent blocks #59606
