📝 WalkthroughWalkthroughThe pull request adds generic container blocks with child constraints, nested editing behavior, rendering frames, HTML serialization, exporter integration, multi-column migration, documentation, examples, and extensive unit and browser tests. ChangesContainer block support
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This should not merge yet: pressing Enter in titled containers can detach existing children or create schema-invalid content, and collaborative column edits can leave resizing targeted at the wrong columns.

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
- function mountChildren(element: HTMLElement | null) { - mountContent(element); - if (!element) { - return; - } - element.dataset.nodeViewContent = ""; - element.setAttribute("data-children-of", blockConfig.type); - const root = element.closest( - "[data-node-view-wrapper]", - )?.firstElementChild; - if (!(root instanceof HTMLElement)) { - throw new Error( - "Container content must be inside its node view wrapper.", - ); - } - applyContainerAttributes<PropSchema>( - root, - blockConfig.type, - block.props, - blockConfig.propSchema, - block.id, - ); - root.toggleAttribute("data-selected", props.selected); - } + const slot = useRef<HTMLElement | null>(null); + const mountChildren = useCallback( + (element: HTMLElement | null) => { + slot.current = element; + mountContent(element); + if (!element) { + return; + } + element.dataset.nodeViewContent = ""; + element.setAttribute("data-children-of", blockConfig.type); + }, + [mountContent], + ); + + // Keep the author's root element in sync with the block state on + // every commit, independent of the mount callback's identity. + useEffect(() => { + const root = slot.current?.closest( + "[data-node-view-wrapper]", + )?.firstElementChild; + if (!(root instanceof HTMLElement)) { + throw new Error( + "Container content must be inside its node view wrapper.", + ); + } + applyContainerAttributes<PropSchema>( + root, + blockConfig.type, + block.props, + blockConfig.propSchema, + block.id, + ); + root.toggleAttribute("data-selected", props.selected); + });

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.
In
`@packages/core/src/extensions/tiptap-extensions/KeyboardShortcuts/KeyboardShortcutsExtension.ts`:
- 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.
In
`@packages/xl-multi-column/src/extensions/ColumnResize/ColumnResizeExtension.ts`:
- Around line 89-98: Update the “resize” handling in ColumnResizeExtension so it
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.

Fix the generated source-alias paths.
From this file's directory, ../../packages/... resolves to examples/packages/..., not the repository-level packages/.... The guard therefore disables the aliases during local development, and the alias entries point to the same invalid location. Use ../../../packages/... and update the generator that produces this file.

Handle an empty titled block before generic empty-block creation.
If a titled block has an empty title and existing children, the branch at Line 1002 runs before this branch. It creates a sibling paragraph, transfers the children to it, and removes the titled block body. Pressing Enter then detaches existing children instead of entering the body.
Move this titled-block handling before the generic empty-block branch, or exclude blocks with owned children from that earlier branch.

Create a child that satisfies children.allow.
This branch always creates a paragraph. If a titled block allows only another child type, such as children: { allow: ["heading"] }, Enter in its title inserts a disallowed paragraph into its body. Derive the default permitted child block from the container configuration instead of hard-coding "paragraph".

Reset resize state when the saved column pair changes structure.
Lines 89-98 only verify that the saved IDs still exist. A collaborative or programmatic transaction can move either column to another column list without changing its ID. The next mouse move then updates widths for a non-adjacent pair or for columns in different lists.
Verify that both columns remain ordered adjacent children of columnList. Return the default state when that invariant fails.

Reset activeFrames between tests.
activeFrames is module state at line 47. It is never reset in afterEach. Line 432 and line 388 assert absolute values (0 and 1). Those assertions therefore depend on every earlier test unmounting its frameAlert frames. If one earlier mount leaks, this assertion fails here and the reported failure points at the export path rather than at the real cause.
Reset the counter in afterEach, after root?.unmount() runs the frame cleanup.

root?.unmount();
root = undefined;
if (div) {
document.body.removeChild(div);
div = undefined;
}

Stacked on #3051 (BlockInfo API refactor) — this branch is rebased onto
refactor/block-info-apiand adopts its vocabulary throughout (producers,NodeSpec.blockConfig, sharedgetInsertionPos); the parallel home-grown implementations are gone.What this adds on top of #3051
Compartments —
content: "inline"+childrencoexist, giving blocks a real rich-text title with a body of child blocks (fixes #2020, #2378). Title/body editing behaves as one unit: Enter splits into the body, Backspace merges back, Shift-Tab stops at the body edge.renderFrame— second hook besiderenderthat draws the box around content + children ({ dom, slot, update? }). Returningundefineddeclines the frame (plain nesting) — the toggle pattern. Pure containers can draw their box inrenderFramealone with in-placeupdate; React renders pure-container frames live and installs compartment frames as static snapshots.Derived repair — dissolve-vs-pad replaces configured strategies: below-
minanywhere-containers dissolve into survivors (counted on content, not padded empties),containerOnlyblocks pad, emptied container children are dropped while emptied regular blocks are kept.Fail-fast validation — bad
content+childrencombos, regular blocks inallow, require-cycles, and missingrender/renderFrameall throw at spec-definition time.Dropped as YAGNI —
