Description

contentOnly mode is becoming more prevalent in the editor after 'Select Mode: Use the content-only behavior in select mode' was merged.

Lots of block types still aren't working perfectly in contentOnly mode, so this list intends to capture those issues so that they can be worked on in parallel by multiple devs. Lots of the blocks also share similar issues, so hopefully there are higher-level solutions to the problems that can be found (lets discuss these in the comments).

Feel free to add more to this issue if you discover untracked issues.

const blockExamples = wp.data.select( 'core/blocks' ).getBlockTypes()
  .filter( ( { example } ) => example )
  .map( ( { name, title, example: { attributes, innerBlocks } } ) => ( { name, title, attributes, innerBlocks } ) );
const createInnerExamples = ( innerBlocks ) => innerBlocks.map( ( { name, attributes, innerBlocks } ) => {
  return wp.blocks.createBlock( name, attributes, createInnerExamples( innerBlocks ?? [] ) );
});
const createExamples = ( examples ) => examples.map( ( { name, title, attributes, innerBlocks } ) => {
  const innerBlockInstances = createInnerExamples( innerBlocks ?? [] );

  return wp.blocks.createBlock( 'core/group', {
    templateLock: 'contentOnly',
    metadata: { name: title }
  }, [ wp.blocks.createBlock( name, attributes, innerBlockInstances ) ]);
});
const innerBlockInstances = createExamples( blockExamples );
const blocks = wp.data.select( 'core/block-editor' ).getBlocks();

wp.data.dispatch( 'core/block-editor' ).insertBlocks( innerBlockInstances, blocks.length );

Blocks

Buttons

• User cannot add/remove individual buttons (see Add new mode to contentOnly locking to allow insertion of new inner blocks #52018)

Cover

• Background image cannot be modified (should it be possible to modify this?)
• Initial block placeholder can't be interacted with in contentOnly mode (possibly the same issue as above).

Details

PR: #70124

• Details block appears as a single 'Paragraph' in the Inspector Content panel

File

PR: #65787

• Block is completely non-interactive, including the placeholder

Gallery

• Placeholder is non-interactive in contentOnly mode.
• Users cannot add/remove items (should they be able to?) (see Add new mode to contentOnly locking to allow insertion of new inner blocks #52018)

List

PR: #65836

• Users cannot add/remove list items from the list block or nest list items (how should nested list items appear in the Inspector content panel?) (see Add new mode to contentOnly locking to allow insertion of new inner blocks #52018)
• List Items currently have a special case in the code to prevent them appearing in the Inspector Content panel (a more general solution to this should be found as other container blocks will have the same kind of problem for their inner blocks):

  gutenberg/packages/block-editor/src/components/block-inspector/index.js

  Line 242 in df27bd9

  getBlockName( current ) !== 'core/list-item' &&

Media / Text

• Additional paragraphs can't be added in the content area of the block (similar to Quote)
• In the Inspector panel, the paragraph that's inside the Media Text block appears after it (again, similar to Quote)

More

PR: #70100

• User cannot edit 'Read more' text

Navigation

• Cannot be edited (see Navigation Block: develop a content-only representation #65699)

Post Title / Featured Image / Excerpt

• Blocks cannot be edited (they have no attributes suitable for the role: content declaration)

Query

• Query Loop Block: develop a content-only representation #66614

Quote

• The paragraph that's inside the Quote appears after the Quote block in the Inspector Content panel (to repro, add a quote block inside a group, apply contentOnly templateLock to the group, and select the group.)
• Users cannot add more paragraphs (should they be able to? If so should they also be able to add other types of blocks? How do these appear in the Inspector Content panel?) (see Add new mode to contentOnly locking to allow insertion of new inner blocks #52018)

Site Logo / Site Title / Site Tagline

PR: #67260

• Blocks cannot be edited (they have no attributes suitable for the role: content declaration)

Social Link(s)

• Social Link: Add contentOnly editing support #66622
• Allow editing individual link text. Should be button be refactored to use <RichText />?
• Should social link block styles be shown in Write mode for each link or only the social links block container?
• Additional blocks cannot be added to Social Links (see Add new mode to contentOnly locking to allow insertion of new inner blocks #52018)

Synced Patterns in Write Mode

PR: #67026

• Write Mode: Non-overridden synced pattern content is editable #66424

Table

PR: #70114

• Block is completely non-editable in contentOnly mode, including the initial placeholder

Template Parts

• Template parts are unselectable in write mode, as they're not considered 'sections'. (see Template part selecting and editing unavailable in “Write” mode #66463)
