… for block plumbing Replaces the BlockInfo union's isBlockContainer/childContainer/blockContent shape with block/content/children, and annotates it with the facts callers kept re-deriving by hand: contentStart/contentEnd, childrenStart/ childrenEnd, contentKind (read off the spec config stored on the node), and isContentEmpty. The +1/-1 position arithmetic around content edges, tables and child ranges moves into blockEdgePos/blockEdgeSelection/ tableContentCaretPos and the ChildrenInfo fields. The six producers collapse to four named by the input you already have: getBlockInfoFromNode, getBlockInfoAt, getBlockInfoNearPos, getBlockInfoFromSelection. Block navigation (parent/prev/next/last- descendant) joins them here instead of living beside the merge command. All block manipulation (insert/move/nest/replace/split/update, selections, clipboard, serialization, conversions, keyboard shortcuts) is rewired onto the new vocabulary. insertBlocks gains "first-child"/"last-child" placements resolved through getInsertionPos, shared with the move commands so "can this block go here?" has one schema-driven answer; hand-written nodes are checked against their declared content kind when the schema is built (checkNodeMatchesConfig).
Resolve block shape directly, validate wrapper structure at the BlockInfo boundary, and convert content from the established content kind. Move insertion resolution into BlockInfo and use node bounds for last-descendant navigation, updating callers and regression coverage.
Build container ownership and editing on the BlockInfo helpers. Keep repair policy centralized, use the existing NodeView lifecycle for JS and React frames, and expose shared helpers through the core entrypoint.
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.
- 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.
Brings in #3124 (nested Backspace) and ports it to this branch's BlockInfo API (`block`, `content`, `children`, `hasContent`, `contentKind`): - mergeBlocks: `mergeIntoParent` and the permissive sibling merge from #3124, in the new field names. The block above may be empty, as in Notion. - KeyboardShortcutsExtension: #3124's Backspace order (merge before un-nest, un-nesting last) and its empty-block handler, in the new names. - keyboardhandlers e2e: take main's `{End}` fix for the flaky caret. - The characterization test for Backspace at the start of a nested first child now expects #3124's merge into the parent.
Brings in main (including #3124, nested Backspace, and #3062, Dark Reader mutations) through #3051. - mergeBlocks: #3124's merge into the parent is the general parent path; its content comes from `getMergeContent`, so an owned plain-text title still takes its first child's text. The sibling merge keeps plain-text handling and no longer refuses an empty block above (as in Notion). - KeyboardShortcutsExtension: #3124's Backspace order (un-nest last) and its empty-block handler; a titled block with children above still takes the move-into-body branch, but the "must be inline" check is gone. - nodeViewMutations: block content node views use #3062's Dark Reader rule. Frames keep ignoring their own chrome via a new `ignoreFrameChromeMutations` (marked TODO(review)). - Keep both sides' new keyboard tests; regenerate the lockfile.
…-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.
A block dragged onto a toggle's title, chevron or "Add block" button becomes its first child, as in Notion. The drop cursor shows the place and the toggle is highlighted like a selected block. - `meta.dropsIntoChildren` marks a block that takes drops this way. - The drop cursor finds the target and a `handleDrop` plugin drops the blocks where the cursor shows them. - Drag-and-drop events on frame chrome now reach ProseMirror. - A toggle stays open when its last child is removed or moved out.
…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").
`handleDrop` used the target from the last `dragover`. If the target was removed in the meantime (e.g. by a collaborator), it threw halfway through the move. It now looks up the target first and lets ProseMirror drop the blocks when it is gone. The drop also clears the highlight.
…O-1236) The block type select filtered a fixed item list by prop names and types. With `allowToggleHeadings: false` it showed no headings at all, and with `levels` it still showed every heading level. `getDefaultBlockTypeItems(editor)` (core) now returns the block types that the schema supports, with their props: headings for the configured levels, toggle headings only when the heading has `isToggleable`. The slash menu and the block type select both use it, each in its own order. Breaking: `blockTypeSelectItems(dict)` is now `blockTypeSelectItems(editor)`.
The block implementation option for keyboard settings is now `experimental_keyboard`. The API is still under discussion and may change. The resolved settings on a schema spec stay at `keyboard`, and the declared option is no longer kept on the spec.
…into container-blocks/toggle-followups
…p isContainerConfig
- nestBlock: `sinkItem` opens its slice into the previous sibling and its block group only, never into the group's last child. Tab after a column list (or any container node) now nests the block instead of throwing. `insert` follows the open depth; the step is applied with `tr.step` again, since the schema cannot refuse it.
- `children.min` is only valid with an `allow` list. `{ allow: "blocks" }` cannot carry it; the type and `validateChildrenConfigs` enforce this. `min: 0` lets a container be empty.
- Remove `isContainerConfig`: it was a plain property check.
- Docs: trim the typst section on blocks that place their children; describe `insertBlocks` placements for all blocks; document the `children.min` rule.
- Cleanups: the mergeBlocks test asserts that children are lifted and the comment names `createChainableState`; `nodeToBlock` loop variable; `contentKind` doc; the Exporter's container check.
- Columns: Enter in an empty column block adds another block (`emptyChildEnter: "stay"`), as in Notion. Other containers keep the default, where an empty last block leaves the container. - Split: the children of a split block follow the text after the caret into the new block again, as on `main`. The new keyboard setting `splitKeepsChildren` keeps them on the block. It defaults to `true` when Enter goes into the children, and closed toggles set it. - `children.exclude` names the container types a container of any blocks does not hold. Columns exclude column lists, as on `main`. The content expression is built when the editor builds its ProseMirror schema, from the complete block specs. - A block's `meta` is resolved once per spec (`resolveBlockMeta`), like its keyboard settings. `draggable` defaults to `false` for a named-only container, which can only live in its parent. - Multi-column drop: dropping blocks onto a target they hold does nothing, instead of throwing `Block with ID ... not found` (a CI flake). - Tests: Backspace at the start of a column's first block keeps the caret; column children; a browser test for the drop flake. - Docs: keyboard settings, `children.exclude`, `meta.draggable`; no column example on the container page.
… rule - A framed block's internal HTML marks its slot (`data-frame-slot-todo`), and the `blockContainer` parse rule reads only that element. Chrome a frame draws outside the slot no longer parses back as a paragraph. TODO: containers mark the same region with `data-children-of`; use one marker once container boxes move into `renderFrame`. - External HTML leaves out `renderFrame`: a frame is editor chrome. A block that wants a wrapper returns one from `toExternalHTML`, with `childrenDOM` for its children. - The test schema's callout always draws its chrome (no `this.renderType` branch), and the framed alert draws the same chrome, so the format-conversion tests cover both. - One implementation of the props to `data-*` attribute rule (`propsToDataAttributes`, `setDataAttributes`, `applyDataAttributes`), used by blocks, inline content, tables, containers and the React specs. No output changes. - Remove `isControl` from the side menu: it made the handle depend on whether a container's chrome is an element or padding.
Side menu files resolved from the container port of #3179 (meta.draggable via isDraggable). blockDOM.ts stays in extensions/ (TableHandles uses it) and gains getBlockElement and getDirectChildBlocks. renderFrame.test.ts no longer imports the removed CONTAINER_SELECTOR.
- A container (`container: true`) declares only `renderFrame`; `render` is not permitted (`validateRenderHooks`). Its frame root carries the block's attributes. - `render` returns only the block's content. Both HTML serializers call `renderFrame` themselves (`renderFrameDOM`). - A block exports its frame unless it has its own `toExternalHTML`, which replaces the content and the frame. The spec has `toExternalHTML` only when the author wrote one. - External HTML treats containers like regular blocks: no `data-node-type`, `data-id` or slot marker; props stay as `data-*`. Columns get `parse` functions, so they still round-trip. A container's children are kept when its own export places them nowhere. - One slot marker (`data-frame-slot`) and finder (`findFrameSlot`). A frame's `dom` is an `HTMLElement`. `renderFrame`'s context no longer has `blockContentDOMAttributes`. - React: frames take `slotRef`; `toExternalHTML` gets `childrenRef` (like core's `childrenDOM`); a container renders through `FrameNodeView`. - `createBlockSpecFromTiptapNode` drops the unused `container`, `children` and `placeable` options. - Main's doc comment for `render`'s `update` hook is restored.
One FrameView type for vanilla and React frames; BlockContainer's node view rebuilt from main's; whoever draws a frame stamps it; shared chrome rules (drag-and-drop and clipboard events go to ProseMirror); getBlockElementForNode for BlockPopover; containers never reuse another block's frame.
A React container's node view `dom` is TipTap's wrapper, which has `display: contents` and so no box. nodeDOM boxes, coordsAtPos at the container's edges, posToDOMRect, the drop cursor, the selection box and scrolling measured 0,0,0,0. This is a workaround: the wrapper's getBoundingClientRect and getClientRects measure the frame's root instead. Other measurements of the wrapper (offsetTop, observers, scrollIntoView on it) stay wrong. The correct fix makes the frame's root the node view `dom` (FIXME in code).
From a background agent, rebased onto container-blocks/unified. - React frames decline with a props-only `hasFrame`, like vanilla frames that return `undefined`. The NodeViewWrapper fallback is removed. - A regular block's frame root replaces `.bn-block` as the block's element: it gets `data-node-type`, `data-id` and the colors. CSS and code that need the block's element use `[data-node-type]`.
Every block now has one node view path (`frameNodeView`): the frame's root is the view's `dom`, and its slot holds the content and children. A regular block without its own frame gets the default frame, `.bn-block-outer > .bn-block`. A custom frame replaces both elements, and its root gets the class `bn-block-outer`. - One stamping function (`stampFrame`) for vanilla, React and the internal HTML serializer. `applyContainerAttributes`, `stampBlockFrame` and `renderBlockElement` are removed. - One internal HTML path for containers and regular blocks (`blockFrameDOM`). The external serializer no longer strips container markers, because `renderFrameDOM` no longer adds them. - `BlockContainer` and container node views share `frameNodeView`.

Preserve block props in the default internal frame.
The fallback creates blockContainer with only id, unlike the previous serializer, which also passed props. Internal HTML can therefore omit attributes such as data-block-style, data-depth, and data-depth-change.

Update the fallback in blockFrameDOM to pass block.props along with block.id
when creating the blockContainer node, preserving block properties in the
default internal frame.

Goal
Every block uses one code path. Before this PR, regular blocks and container blocks used different paths for the node view, the attributes of a frame's root, and internal HTML. With this PR:
.bn-block-outer > .bn-block) is a frame: the default frame.dom, and the frame's slot holds the content and children.renderFrame) replaces the whole default structure, the same as a container's frame.The result must make the code simpler. Without tests and CSS, the source changes by +365 / −445 lines compared with
container-blocks/unified(−80). Before the second commit, it was +127.Commits

TheNodeViewWrapperfallback is removed.renderFramemust return an element; it cannot returnnull..bn-blockas the block's element.frameNodeView(inframe.ts) is the node view of every block.BlockContainer.addNodeViewis one call to it.containerNodeViewandframeNodeViewHooksare removed.frameView), from a vanillarenderFrame, or from the default frame. Theunframedspecial case and the code that replaced.bn-blockwith a frame's root are removed.stampFrameis the only function that stamps a frame's root, for vanilla, React and internal HTML. It replacesstampContainerFrame,applyContainerAttributes,stampBlockFrameandrenderBlockElement.blockFrameDOM): the frame, then the content in the slot, then the children.renderFrameDOMno longer adds markers, so the external HTML serializer no longer removes them from containers.DOM

On
main, a toggle's chrome is in its content node view.container-blocks/unifiedalready moves it into a frame, so the DOM of toggles changes in #3059 in all cases.Caveats
domof a React frame is TipTap's wrapper, which hasdisplay: contents. ProseMirror puts node decorations on thatdom: thedata-prev-*animations and the drop target. Also the indent lines (::before) are on that element. An element withdisplay: contentsshows no margins, transitions or pseudo-elements. Onunified, a React frame on a regular block is inside.bn-block-outer, so this is a regression for those blocks. Containers already have this problem onunified. ThemeasureFrameRootworkaround fixes only measurements, not decorations..bn-blockdoes not select blocks with a frame, toggles included. Use[data-node-type="blockContainer"].overriding-css.mdxis updated.domAttributes.blockdoes not reach a frame's root, neither the class nor the other attributes (see BLO-1386).data-node-type="blockContainer". Old HTML (a frame inside.bn-block) still parses; a test covers it.renderFramecannot returnnull; usehasFrame.Follow-ups before merge
dom, not TipTap's wrapper (see theFIXMEonmeasureFrameRootand Layout blocks and block frames (preview) #3059, review thread r4084731902). Without it, the first caveat stays.performance.test.ts(jsdom) shows no change: 1.5 ms for each keystroke in 5000 headings. Do these tests also:frameNodeView);updatehook.data-prev-*), the indent lines and the drop highlight on toggles and on custom frames, by hand.hasFrame;domAttributes.blockon a frame's root (removed or copied);renderFrame..bn-block.Tests
