… 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.

withGeneratedIdsalways rebuilds the whole subtree. In the common case the children were built byblockToNode, which already assigns an id to every block, so the rebuild mints nothing and only allocates.The cost compounds with nesting.
blockToNoderecurses, so for a chain ofdnested containers the innermost subtree is passed throughwithGeneratedIdsonce per enclosing container level. That makes container conversion O(d × n) instead of O(n).Rebuild only the branches that actually change.

452-475: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winSeparate attribute synchronization from the content mount.
mountChildrenis re-created on every render. React therefore calls the previous ref withnulland the new ref with the element on each render. Two effects follow from that:
applyContainerAttributesand thedata-selectedtoggle only stay in sync because the ref identity is unstable. If a later change memoizesmountChildren, prop and selection updates stop landing on the author's root, and the test atReactBlockSpec.container.browser.test.tsxlines 161-171 would be the only signal.- TipTap's content host detaches and re-attaches on every container render, including renders caused by author-local state, which is DOM churn inside the editable region.
FrameNodeViewalready memoizes its mount callback on[mountContent]. Use the same shape here, and apply the attributes in an effect that depends on the block props, the id, andprops.selected.♻️ Proposed split of mounting and attribute sync

In `@examples/06-custom-schema/12-alert-blocks/vite.config.ts`:
- Line 16: Update the source-alias paths and existence guard in the Vite
configuration from ../../packages/... to ../../../packages/... so they resolve
to the repository-level packages directory. Also update the generator that
produces this configuration to emit the corrected paths, including the alias
entries referenced by the comment.
In `@examples/06-custom-schema/13-callout-block/vite.config.ts`:
- Line 27: Update the source alias paths used by the Vite configuration
generator for `@blocknote/core` and `@blocknote/react` from ../../packages/... to
../../../packages/... so they resolve to the repository packages directories,
then regenerate the generated vite.config.ts file.

- Around line 1042-1045: Update the Enter handling around the titled-block
branch so an empty titled block with existing children is handled before the
generic empty-block creation path. Preserve the existing children as the titled
block’s body and enter that body instead of creating a sibling paragraph or
detaching the children; use the nearby titled-block and empty-block conditionals
to make the ordering or exclusion change.
- Around line 1073-1076: Update the Enter-handling branch that creates newBlock
to derive its child type from the blockContainer configuration’s permitted
children instead of hard-coding the paragraph node. Ensure the created child
satisfies children.allow, including titled blocks that permit only types such as
heading.

verifies that leftColumn and rightColumn are still adjacent, ordered children of
columnList, not merely present by ID. Return the existing default state when
either column belongs to another list or the pair is non-adjacent; otherwise
preserve the current state update.
In `@tests/src/unit/react/reactFrame.test.tsx`:
- Line 432: Reset the module-level activeFrames counter in the test suite’s
afterEach hook after root?.unmount() performs frame cleanup, so each test starts
from a known state and the absolute assertions remain reliable.

882-884: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick winMove the titled-block Enter handler before the generic empty-block handler.
For an empty title with existing children, the generic handler runs first, moves the body into a sibling, and deletes the original child range. The titled-block handler preserves the body by inserting the new block inside it. Reorder these handlers so the titled-block handler handles this case first.

`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
YousefED

…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.

Builds on #3051 (BlockInfo API refactor), which is merged into
main. This PR now holds the complete container-blocks work: the original container and frame API, plus #3142 (keyboard settings and the container flag) and #3143 (toggle drop and menu block types), which were merged into this branch. Their descriptions have the details of each part.What changes
1. Container blocks and frames
container: trueand must havecontent: "none".childrensays which child blocks it accepts:{ allow: [...], min }. Every other block accepts any child blocks.renderFrameis a second hook next torender. It draws the box around a block's content and children:{ dom, slot, update? }. Returningundefineddeclines the frame, so a block can decide this from its props or children.mindissolves into its remaining children. Blocks that can only live in a container are padded.contentandchildrencombinations, regular blocks inallow, require cycles, and a missingrenderorrenderFramethrow when the spec is defined.{ withChildren }when the mapping places the rendered children itself. A container with a plain mapping throws..bn-block, so they reach the children of any framed block.09-container-block(a panel with a live frame) and13-callout-block(a titled block with a body).2. Keyboard settings (from #3142)
A block implementation has an
experimental_keyboardoption: only the settings that differ from the defaults, or a function of the block that returns them. The option is marked experimental because the API is under discussion and may change.enter"split","into-children","line-break""split"shiftEnter"line-break","same-as-enter""line-break"splitKeepsTypefalseresetsTo{ type, props? }{ type: "paragraph" }emptyEnterResetsfalseemptyChildEnter"outdent","exit-at-end","stay""outdent"(containers:"exit-at-end")childrenCanOutdenttrue(containers:false)The central Enter and Backspace handlers read these settings in a fixed order. List items declare
splitKeepsTypeandemptyEnterResets, so they no longer need their own Enter handler. The toggles use the function form: Enter goes into the children only while the toggle is open.meta.hardBreakShortcutis deprecated.The built-in toggles are built with
renderFrame(createToggleFrame). The chevron has an accessible name andaria-expanded. A toggle heading turned into a regular heading stops being a toggle.Backspace keeps a block's identity: below an empty block of the same type and props, the block moves up into its place and keeps its id. Below an empty block of another type, the text moves into that block, as in Notion.
3. Toggle drop and menu block types (from #3143)
meta.dropsIntoChildren.getDefaultBlockTypeItems(editor)in core returns the block types that the schema supports, with their props. The slash menu and the block type select both use it, each in its own order. The block type select now shows headings when toggle headings are disabled, and only the configured heading levels.Issues
createHeadingBlockSpec#2347: the block type select shows only the configured heading levels (BLO-990).Breaking changes
createToggleWrapper(core) andToggleWrapper(React) are removed. UserenderFramewithcreateToggleFrame. The toggleable-blocks example is removed.data-show-children. Use.bn-toggle-button[aria-expanded].meta.hardBreakShortcutis deprecated. Useexperimental_keyboard.enterandexperimental_keyboard.shiftEnter.blockTypeSelectItems(dict)is nowblockTypeSelectItems(editor): the items depend on the schema.container: trueand needs a{ withChildren }exporter mapping.Known gaps
TODO
container: truebefore release. Candidates:container: true,layoutBlock: true,frameOnly: true.frameOnlyonly fits if a container draws its box inrenderFrameinstead ofrender.experimental_keyboard): declarative settings vs. lower-level primitives (see the discussion on feat(core): split keyboard behaviour from container structure #3142).Review checklist
The open review threads on this PR, grouped. Each one is resolved when its item is done or moved to a follow-up issue.
