feat(core): split keyboard behaviour from container structure by YousefED · Pull Request #3142 · TypeCellOS/BlockNote

YousefED · 2026-09-30T08:03:50Z

Builds on #3059. This PR separates how the keyboard treats a block from how the block is structured.

Why

After the tabs and stepper examples (#3140), I moved the built-in toggle blocks to the frame API (renderFrame). The frame part worked for about 90% of the cases immediately: the chevron, the "Add block" button and the open state all moved into a frame with less code than before.

The keyboard part did not fit. A toggle needs some behaviour of a "titled" block, but not all of it:

When the toggle is open, Enter in its text must go into its children (as in Notion). When it is closed, Enter must split the block.
Enter in an empty child must add another child. It must not leave the toggle and it must not outdent.
Shift-Tab must still move a block out of the toggle. For a toggle, children are nesting, not a body.

In #3059, all of this came from one flag: children on a block with content. That flag switched on a fixed set of behaviour, in 21 places in 8 files (hasOwnedChildren in the keyboard handlers, merge, nest, update, block info, the exporter and the validator). A block could only have all of that behaviour or none of it, and the behaviour could not depend on props or on view state (open or closed).

So the conclusion was: keyboard behaviour must be a separate, explicit setting on the block, and the structure must be a separate, explicit flag.

What changes

1. Keyboard settings on the block implementation

A block implementation has a keyboard option: only the settings that differ from the defaults, or a function of the block that returns them.

Setting	Values	Default
`enter`	`"split"`, `"into-children"`, `"line-break"`	`"split"`
`shiftEnter`	`"line-break"`, `"same-as-enter"`	`"line-break"`
`splitKeepsType`	boolean	`false`
`resetsTo`	`{ type, props? }`	`{ type: "paragraph" }`
`emptyEnterResets`	boolean	`false`
`emptyChildEnter`	`"outdent"`, `"exit-at-end"`, `"stay"`	`"outdent"` (containers: `"exit-at-end"`)
`childrenCanOutdent`	boolean	`true` (containers: `false`)

The schema fills in the defaults once. The spec then holds a function that returns every setting, so the handlers do not check for missing values. A setting given as undefined keeps its default.

Examples:

// Bullet list item
keyboard: { splitKeepsType: true, emptyEnterResets: true },

// Toggle list item: depends on view state
keyboard: (block) => {
  const open = isToggleOpen(block);
  return {
    splitKeepsType: true,
    emptyEnterResets: true,
    enter: open ? "into-children" : "split",
    emptyChildEnter: open ? "stay" : "outdent",
  };
},

// Callout with a title
keyboard: { enter: "into-children", childrenCanOutdent: false, emptyChildEnter: "exit-at-end" },

The central Enter and Backspace handlers read these settings and apply them in a fixed order. The order is documented on the BlockKeyboard type. meta.hardBreakShortcut is deprecated. It still works as the default for enter and shiftEnter.

2. `container: true` marks a container

A container (a block whose own node holds its child blocks, such as a column list) now declares container: true. It must have content: "none". The type and the validator enforce this.

children now has one meaning: which child blocks a block accepts. The default is { allow: "blocks" } for every block. Only a container can restrict the types or set a minimum count, because the children of other blocks share one untyped group.

{ type: "callout", content: "none", container: true }
{ type: "columnList", content: "none", container: true, children: { allow: ["column"], min: 2 } }

3. Exporters: the mapping decides where children go

A block mapping is a plain function (the exporter places the children, indented) or { withChildren } (the mapping receives the rendered children and places them). The shape of the mapping decides where the children go. The only container check left: a container with a plain mapping throws, so the error comes early.

4. Toggles

The built-in toggles use createToggleFrame with renderFrame.
The chevron has an accessible name and aria-expanded. The CSS also reads aria-expanded, so data-show-children is removed.
A toggle heading changed to a regular heading with the keyboard shortcut, the markdown rule (## ) or the slash menu stops being a toggle. The block type menu already did this (fix: BlockTypeSelect item filtering based on schema #2112).

5. Block colors with frames

.bn-block carries the block's text and background color. The block container's node view and the internal HTML serializer set them. The 18 color rules in Block.css no longer look for the content as a direct child. Thus colors reach the children of any framed block, also custom ones, and the toggle-specific copies of these rules are removed.

Benefits

Combinations that were not possible before:
- A block with content whose keyboard behaviour depends on props or view state (a toggle heading, an open or closed toggle).
- A block that sends Enter into its children but lets Shift-Tab move blocks out (a toggle), or keeps them in (a callout).
- A block where Enter inserts a line break (a diagram), without a meta flag.
- A custom framed block whose colors apply to its children.
Less implicit behaviour: before, adding children to a block with content changed the keyboard, merge, nest, update and export behaviour in 21 places. Now each concern has its own explicit setting: container for structure, keyboard for keys, the mapping shape for export. Changing one does not change the others.
Lists are first-class: the list Enter handling was a separate Enter shortcut in each list block (listItemEnterHandler.ts), plus an unused copy (ListItemKeyboardShortcuts.ts). Now list items declare splitKeepsType and emptyEnterResets, and the central handlers apply them in the same order as for every other block.
Less toggle code: createToggleWrapper (197 lines) and the React ToggleWrapper (162 lines) are replaced by createToggleFrame (127 lines) for both toggles.

Issues

Closes Hitting enter on a unfolded toggle block creates new toggle block #1875: Enter on an open toggle adds a block inside the toggle (BLO-929).
Closes Enter Key Breaks Children in Custom Toggleable Blocks #2020: Enter no longer breaks a toggle's children (BLO-949).
Closes Toggle block content is moved to next toggle block #2378: Enter on a closed toggle keeps its children in the toggle (BLO-998).
Closes Cannot convert Toggle Heading to regular Heading — it remains collapsible #2124: the type menu part was fixed by fix: BlockTypeSelect item filtering based on schema #2112. The shortcut, markdown and slash menu paths are fixed here (BLO-959).
Closes Collapsible list: unlabeled accessible button, decorative image #2811: the toggle button has an accessible name and state (BLO-1218). This overlaps with fix(core): give the toggle button an accessible name and state #3133.
Closes Preserve block identity when editing from the block's start #550: editing at the start of a block keeps the block's identity.
- Enter at the start of a block keeps the block's id, props and children.
- Backspace below an empty block of the same type and props moves the block up into its place. The block keeps its id, props and children. Delete at the end of the empty block does the same.
- Backspace below an empty block of another type (for example an empty heading) moves the text into that block, which keeps its id, type and props, as in Notion (feat: Update backspace handling in nested blocks (BLO-1326) #3124).

Also fixed:

Backspace at the start of a paragraph after a code block with an indented child did nothing. It now joins the paragraph to that child.
The core unit tests sometimes failed with "document is not defined". The placeholder extension changed the editor element's class outside ProseMirror, and ProseMirror read this change 20ms later, sometimes after the test environment was removed. The class is now set through ProseMirror's attributes prop. tiptap makes the same kind of change when it creates the view, so this makes the failure less frequent, but does not remove it.

New regression tests for fixes that had no test: #1672 (Shift-Enter keeps styles), #2566 (Backspace moves the caret to the last nested block), #605 (Backspace below an image deletes only the empty block).

Breaking changes

Compared with main:

createToggleWrapper (core) and ToggleWrapper (React) are removed. Use renderFrame with createToggleFrame.
The toggleable-blocks example is removed.
Toggles no longer have data-show-children. Use .bn-toggle-button[aria-expanded].
meta.hardBreakShortcut is deprecated. Use keyboard.enter and keyboard.shiftEnter.

Compared with #3059 (not released):

A block with content cannot declare children restrictions. Use keyboard settings for the behaviour.
A container must declare container: true.
A container needs a { withChildren } exporter mapping.
BlockInfo.hasOwnedChildren is removed.

Known gaps

feat: Update backspace handling in nested blocks (BLO-1326) #3124 (merged in) makes every first child merge into a parent with inline content on Backspace. It replaces this PR's interim rule for "titled" blocks. Blocks with plain-text content never take merged text. So in a plain-text block with enter: "into-children", Backspace at the start of the first child un-nests it, or does nothing when childrenCanOutdent is false.
The block colors need a node view on every block. If blocks without a frame stop getting a node view (review comment on Container blocks: compartments, renderFrame, repair, validation, exporters #3059), unframed blocks need the old direct-child color rules back.
A toggle does not stay open when its last child is removed or moved out, and a block cannot be dropped into an empty toggle (BLO-956). Both are it.fails tests here, and feat(core): drop a block into a toggle (BLO-956) #3143 fixes them.
In an empty toggle heading, the slash menu's "Heading 2" converts the block. Notion keeps the toggle heading and inserts a new heading below it.
Improve delete key behavior near image blocks #1478 is reopened: Backspace at the start of text below an image still deletes the image.

TODO

Decide the name of container: true before release. The flag means: the block has no content of its own, and its node holds only its child blocks. Candidates: container: true (today), layoutBlock: true, or frameOnly: true. frameOnly only fits if a container draws its box in renderFrame instead of render (today renderFrame is refused on containers), so decide both together.

Testing

After the merge of #3059 (which brings in main with #3124):

Unit: the complete suite passes (core 1,038, tests 958, and every package).
Browser (Docker, Chromium, Firefox and WebKit): the toggle, container, frame, block color, block identity, keyboard handler, multi-column, custom block and copy-and-paste suites pass. The only failures are the tests marked it.fails.
Lint passes.

The commits split the work by topic for review. Only the complete PR is tested, so please squash on merge.

Summary by CodeRabbit

New Features
- Added configurable keyboard behavior for custom blocks, including how Enter and Shift+Enter work, how blocks split or reset, and whether child blocks can be outdented.
- Toggle headings and list items now support expandable content, persistent open states, and improved keyboard editing.
- Added localized labels for toggle controls across supported languages.
- Export mappings can now incorporate rendered child blocks into a block’s output.
Improvements
- Custom container blocks use an explicit container setting, with updated guidance and examples.
- Improved color rendering for nested blocks and HTML exports.
Removals
- Removed the toggleable-blocks example and the standalone ToggleWrapper component.

Tests for the toggle heading and the toggle list item, covering the toggle bugs under BLO-1018 and the rest of their editing behaviour. Every test runs for both blocks. The expected behaviour is Notion's (compared on 2026-09-29), with one exception: a toggle heading turned into a regular heading keeps its children nested. Tests for behaviour that BlockNote does not have yet use `it.fails`, so they fail once it is implemented and must then be changed to `it`: - Enter at the end of an open toggle's title adds a first child (BLO-929) - Enter mid-title moves the rest of the title into a first child (BLO-949) - Enter on an empty last child adds another child - Backspace at the start of the first child merges into the title (fixed by #3124) - the toggle stays open when its last child is removed or moved out - Enter in an empty toggle heading makes a regular heading - Mod-Alt-2 and the slash menu turn a toggle heading into a regular heading (BLO-959) - ArrowDown moves out of an open, empty toggle (BLO-956) - a block dropped into an open, empty toggle becomes its child (BLO-956) Keyboard and open-state tests are browser unit tests next to the toggle code. Drag and drop, the side menu and the placeholder need the full editor view, so they are end-to-end tests.

The toggle heading and the toggle list item now draw their chevron and "Add block" button with `renderFrame` (`createToggleFrame`), instead of wrapping their content with `createToggleWrapper`. `render` draws only the heading or paragraph. - The toggle logic goes from about 200 to about 100 lines: the frame's `update` hook replaces an editor-wide `onChange` listener per toggle, and `ignoreMutation`, `destroy` and the listener clean-up go away. - A heading that is not toggleable gets no frame. - ArrowDown now moves the caret out of an open, empty toggle (BLO-956): the "Add block" button no longer sits inside the content element. - The frame keeps the `bn-toggle-wrapper` class and `data-show-children`, so existing CSS and the internal HTML export still find it. A frame moves `.bn-block-content` one level down, and `Block.css` selects it as a direct child of `.bn-block` in many places. Heading sizes and the block colours that also apply to a block's children therefore get a second selector for the toggle frame. The chevron rotation now applies only to a toggle's own chevron, so a closed toggle nested in an open one keeps its chevron. `createToggleWrapper` and the React `ToggleWrapper` stay, because custom blocks use them.

Blocks declare how the keyboard treats them with a `keyboard` option on their implementation (Enter, Shift-Enter, reset, empty-child Enter, outdenting), instead of deriving it from a `children` config. A container is marked with `container: true`; `children` only restricts its child types or count, and defaults to `{ allow: "blocks" }` for every block. - List items and toggles declare their Enter behaviour as settings; the per-block list Enter handlers and the unused ListItemKeyboardShortcuts file are removed. - Enter at the start of a non-empty block inserts an empty block above, so the block keeps its id, props and children (#550). - Toggles: Enter on an open toggle goes into its children, a closed toggle keeps them; the chevron has an accessible name and `aria-expanded`, which also drives the CSS (replaces `data-show-children`). - A toggle heading turned into a regular heading by the shortcut, the markdown rule or the slash menu stops being a toggle. - Backspace after a block whose own content is not rich text (a code block) merges into its last child block. - Removes `createToggleWrapper`, the React `ToggleWrapper` and the toggleable-blocks example; `meta.hardBreakShortcut` is deprecated.

A block mapping is a plain function (the exporter places the block's children) or `{ withChildren }`, which receives the rendered children and places them itself. A container with a plain mapping throws.

The block's element (`.bn-block`) carries its text and background color, set by the block container's node view and the internal HTML serializer. The color rules in Block.css no longer look for the content as a direct child, so they work when a frame puts the content at any depth, and the toggle specific copies go away.

📝 Walkthrough

Walkthrough

Block schemas now identify containers explicitly and define keyboard behavior through block settings. Toggle blocks use a dedicated frame. Exporter mappings can receive rendered children, and block colors are applied to nested content.

Changes

Container and editor behavior

Layer / File(s)	Summary
Container and keyboard configuration `packages/core/src/schema/blocks/`, `packages/core/src/api/blockManipulation/containers/`, `packages/react/src/schema/ReactBlockSpec.tsx`, `packages/xl-multi-column/src/blocks/Columns/index.ts`, `docs/content/docs/features/custom-schemas/`, `examples/06-custom-schema/09-container-block/`, `tests/src/unit/*`	Block schemas add `container: true` for container blocks. `children.allow` defaults to `"blocks"`, while non-default child restrictions require a container. The schema and documentation expose keyboard settings and update container examples.
Keyboard commands and block editing `packages/core/src/extensions/tiptap-extensions/KeyboardShortcuts/`, `packages/core/src/api/blockManipulation/commands/`, `packages/core/src/api/blockManipulation/containers/`, `packages/core/src/blocks/ListItem/`, `packages/core/src/extensions/SourceBlockWithPreview/`, `packages/react/src/blocks/SourceWithPreview/`, `packages/diagram-block/`, `packages/math-block/`	Enter, Shift-Enter, Backspace, and outdent handling use per-block keyboard settings. Merge behavior distinguishes title content, and list-item Enter handling moves to block keyboard configuration. Source preview and diagram blocks use `keyboard.enter` for line breaks.
Toggle block rendering and interactions `packages/core/src/blocks/Heading/block.ts`, `packages/core/src/blocks/ListItem/ToggleListItem/block.ts`, `packages/core/src/blocks/ToggleWrapper/`, `packages/core/src/editor/Block.css`, `packages/react/src/blocks/ToggleWrapper/`, `packages/core/src/i18n/locales/`, `tests/src/end-to-end/toggleblocks/`, `examples/06-custom-schema/13-callout-block/*`	Toggle headings and list items use a frame with an accessible control and persisted open state. Keyboard settings control entry into and exit from child blocks. The old `ToggleWrapper` implementation and toggleable-block example are removed. Tests and locale strings cover toggle controls and behavior.

Block color rendering

Layer / File(s)	Summary
Color attributes and validation `packages/core/src/pm-nodes/BlockContainer.ts`, `packages/core/src/api/exporters/html/util/serializeBlocksInternalHTML.ts`, `packages/core/src/editor/Block.css`, `packages/core/src/editor/blockColors.browser.test.ts`	Block color attributes are set on content DOM elements during rendering and HTML serialization. Browser tests check nested content, parent color updates, and generated HTML.

Child-aware exporter mappings

Layer / File(s)	Summary
Mapping contract and export dispatch `packages/core/src/exporter/{mapping.ts,Exporter.ts}`, `packages/core/src/exporter/Exporter.test.ts`, `docs/content/docs/features/export/typst.mdx`	Exporter mappings distinguish ordinary callbacks from `withChildren` callbacks. The exporter supplies rendered children to the latter and rejects a plain mapping for a container.
Exporter mappings and tests `packages/xl-docx-exporter/`, `packages/xl-email-exporter/`, `packages/xl-odt-exporter/`, `packages/xl-pdf-exporter/`, `packages/xl-typst-exporter/*`	Default column mappings and test mappings use `withChildren`. Exporter traversal checks whether a mapping places its children.

Merge Risk: 🔵 Low · up to 3bdd9

The change is mergeable. One keyboard test skips the new keyboard-configured plain block on Shift-Enter, so a regression on that path could go unnoticed. Switching the test to the parameterized block type fixes it.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use the parameterized plain block type in the Shift-Enter test.

Line 751 hardcodes "hardBreakEnterPlain". The keyboard case of describe.each therefore never tests keyboardEnterPlain on Shift-Enter. The keyboard.enter: "line-break" path for plain blocks on Shift-Enter has no coverage.

💚 Proposed fix

- const editor = createEditor("hardBreakEnterPlain"); + const editor = createEditor(plain);

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change

const editor = createEditor("hardBreakEnterPlain");

const editor = createEditor(plain);

commit: 2159763

- Restore the toggle heading size and weight rules, which the block color change dropped, and test that a toggle heading looks like a heading. - Keep a keyboard setting's default when a keyboard function returns it as `undefined`, instead of crashing Backspace. - Resolve a block's keyboard settings against the document of the command that asks. - Tests: cover Shift-Enter on plain blocks with `keyboard` settings, remove the per-exporter "unmapped block" tests (core tests the error) and a duplicate Enter test, and update stale comments and names.

…-rules Brings in main (#3124 nested Backspace, #3062 Dark Reader mutations) through #3051 and #3059, and consolidates #3124 with the keyboard settings. - mergeBlocks: #3124's merge into the parent replaces the interim "title's first child" code. `isTitle` is removed: only inline content merges, so a block with plain-text content never takes merged text (documented on `enter: "into-children"`). The block above may be empty (Notion). - KeyboardShortcutsExtension: #3124's Backspace order (merge before un-nest); the final un-nest step respects `childrenCanOutdent`. - Tests: keep both sides' keyboard tests; the block identity test for Backspace below an empty block now expects the Notion behaviour; the plain-text title merge test is removed. - Keep the toggleable-blocks example deleted; reconcile the lockfile; regenerate example files for main's template.

…550) Backspace at the start of a block below an empty block with the same type and props moves the block up into its place: it keeps its id, props and children. Below an empty block of another type, the text still moves into that block, which keeps its id, type and props (Notion, #3124). Delete at the end of the empty block does the same. Also: the placeholder extension sets its editor class through ProseMirror's `attributes` prop instead of on `view.dom`. ProseMirror flushed the outside change 20ms later, which could outlive the editor in tests ("document is not defined").

feat(exporters): let block mappings place their children

cd6bd89

A block mapping is a plain function (the exporter places the block's children) or `{ withChildren }`, which receives the rendered children and places them itself. A container with a plain mapping throws.
