Summary

  • When textBlockStyles are configured on createTipTapRichTextBlock, the toolbar's style dropdown always offered an unstyled "Default" entry alongside the configured styles, even for setups where every heading/paragraph should always carry one of them.
  • Add a requireTextBlockStyle option that removes that entry for text block types with at least one applicable style. The editor auto-assigns the first applicable style wherever one would otherwise be missing (toolbar changes, markdown input rules, keyboard shortcuts, pasted content), via a ProseMirror appendTransaction plugin so no path can leave a node unstyled. The API package rejects stored content missing a required style during validation, consistent with how maxTextBlocks/listLevelMax are already enforced server-side.
  • Enabled the option on the demo's general-purpose rich text block as a usage example (not just a heading-only case).

Prompted by PHSB2C-13678: the TipTap-based Headline block always showed a "Default" style state that didn't exist in the previous Draft.js implementation.

🤖 Generated with Claude Code

Mirrors the admin-side requireTextBlockStyle option: rejects stored
content where a heading or paragraph has an applicable textBlockStyles
entry but none set, consistent with how maxTextBlocks and listLevelMax
are already enforced server-side rather than trusting client-only
validation.
Consumers configuring textBlockStyles previously always got an
unstyled "Default" entry in the toolbar's style dropdown alongside
the configured styles, even when every heading/paragraph should
always have one of them. The new requireTextBlockStyle option removes
that entry and auto-assigns the first applicable style wherever one
would otherwise be missing (toolbar changes, markdown input rules,
keyboard shortcuts, pasted content), via a ProseMirror
appendTransaction plugin so no path can leave a node unstyled.
Shows the option applied to the general-purpose rich text block, not
just a heading-only use case.
@VPS-Andreas VPS-Andreas self-assigned this Aug 21, 2026
maxTextBlocks's trim-on-paste logic in createTipTapRichTextBlock's
onUpdate deleted from `pos + 1` to `doc.content.size + 1`, treating
doc like a regular node whose content starts one position past its
own opening token. doc has no such token — its content starts at
position 0 — so the +1 pointed past the end of the document. Most
reliably reproducible with maxTextBlocks: 1, where it threw and
aborted the whole onUpdate handler, silently skipping requireTextBlockStyle's
backfill on any subsequent transaction within the same handler call.

see #6004 (comment), I think that will also solve your issue

Shows two TipTapRichTextBlock editors side by side with the same
textBlockStyles config, so the effect of requireTextBlockStyle (the
"Default" dropdown entry being offered or not) is visible without
reading through the existing play()-driven interaction test.

Review Change StackReview Change Stack

📝 Walkthrough

Walkthrough

The change adds required text block style handling to the TipTap admin editor and CMS API. The editor assigns applicable styles and hides the Default option. The API validates required styles. The change also fixes maxTextBlocks deletion positions.

Changes

TipTap text block style enforcement

Layer / File(s) Summary
API validation contract
packages/api/cms-api/src/blocks/tipTap/createTipTapRichTextBlock.ts, .changeset/tiptap-require-text-block-style-api.md
The API adds requireTextBlockStyle, validates applicable paragraph and heading styles, and rejects missing styles or invalid configuration.
Admin editor behavior
packages/admin/cms-admin/src/blocks/tipTap/*, demo/api/src/common/blocks/tip-tap-rich-text.block.ts, .changeset/tiptap-require-text-block-style.md, .changeset/tiptap-max-text-blocks-trim-position.md
The editor auto-assigns applicable styles, hides the Default option, updates the demo and stories, and uses zero-based positions for excess block deletion.

Merge Risk: 🟡 Moderate · up to db028

Enabling the new mandatory text block style behaves correctly for newly created content, but editors opening existing content that predates styles may be unable to save it without touching the text, and the style dropdown no longer lets users clear a list style. The server-side check also accepts style names that are not configured for the block type. These should be addressed before merge; the change does not otherwise break existing editing flows.

Backfill legacy content during editor initialization.

input2State passes stored content directly to useEditor. This extension only runs after a document-changing transaction. If a user opens a legacy paragraph or heading without textBlockStyle and saves without editing, the missing attribute remains in state. The API then rejects the submission when an applicable style is required.

Normalize applicable nodes before initializing the editor, or dispatch an initialization transaction that updates state.

Keep Default available for list styles.

activeTipTapTextBlockType identifies ordered and unordered lists, and applicableTextBlockStyles can contain styles for those types. When requireTextBlockStyle is true, the current condition hides Default even when the active list has no textBlockStyle. With a list-only configuration, API validation allows that unstyled list because no style applies to its paragraph nodes. The Select then has value "" but no matching item, so users cannot clear the list style.

Only hide Default when the active text block is a paragraph or heading with an applicable style.

Validate textBlockStyle against configured styles.

ProseMirrorNode.fromJSON(schema, value) does not validate these values because TextBlockStyleParagraph and TextBlockStyleHeading define only default: null. The subsequent predicate accepts any truthy content.attrs?.textBlockStyle, so unknown or inapplicable styles can bypass requireTextBlockStyle. Require a configured style applicable to the current text block type; treat a missing appliesTo as unrestricted.
