Overview 

General HTML Support is a feature of :entity:organization:TYPO3 CMS that works together with existing Processing YAML styling and the RTE configuration.

It allows developers and editors to keep using their existing custom HTML structure along with RTE_ckeditor_pack HTML settings, without needing extra custom development.

Purpose 

This feature helps you to:

• Use your existing project-specific HTML
• Combine Processing YAML rules with the RTE setup
• Keep approved HTML tags, classes, and attributes
• Make the editor more flexible in a controlled way

How It Works 

By default, activating HTML support does not automatically permit any additional markup. Instead, all allowed elements must be clearly defined in the General HTML Support configuration.

This includes defining:

• permitted HTML elements (for example: section, div, article, span, iframe)
• allowed attributes (such as id, data-*, class, style)
• approved CSS classes and styles

After configuration:

• The editor accepts the defined HTML
• Allowed HTML is kept while editing
• Content is saved without removing approved markup
• Any HTML that is not allowed will be automatically removed

Important Note 

This feature only keeps the HTML that is clearly allowed in the configuration. - Allowed HTML elements and attributes will stay in the content - Not allowed or undefined HTML will be removed automatically

For example:

• If div is allowed, it will remain in the content
• If div is not allowed, it will be removed when the content is processed

Configuration Requirements 

Follow the exact configuration steps demonstrated in the Interactive guide below. Once the link is available, review the demo to ensure your setup matches the showcased order of actions before enabling the features in production.

• Configuration Guide

Configuration 

Adjust the AI configuration as needed. To enable the Chat feature, load the AIChat plugin in your CKEditor configuration. When enabled, a Chat button appears in the AI interface together with access to chat history.

1. Working with the Document 

CKEditor AI Chat operates in the context of the active document. Reference specific paragraphs, request full-document proofreading, or ask questions about the currently visible content. Optional Web search and Reasoning features extend the assistant with real-time information and advanced logical processing.

2. Making Changes to Content 

Request summarization, rewriting, or structural improvements. Instead of dumping plain text, AI Chat returns proposed edits that you can review, accept, reject, or convert into Track Changes suggestions—eliminating copy/paste workflows.

3. Brainstorming and Content Creation 

Start from a blank page, generate ideas, build outlines, and refine drafts entirely through conversation. The AI can rewrite, proofread, or polish text whenever needed.

4. Integration 

Enable the Chat feature by loading the AIChat plugin. Once active, the Chat button appears in the AI panel along with chat history controls.

5. Available Models 

Users pick from available AI models via the selector at the bottom of the chat panel. The chosen model remains active for the conversation; start a new chat (+ New chat) to switch models.

6. Web Search 

Web search lets AI retrieve real-time facts, verify information, and generate up-to-date responses. Activate it with the Enable web search toggle for compatible models.

7. Reasoning 

Reasoning enhances problem solving, contextual analysis, and structured outputs. Turn it on with Enable reasoning when the model supports it.

8. Adding Context to Conversations 

Use Add context to attach URLs, files, or documents. The AI analyzes the supplied material to provide summaries, explanations, or answers. Integrations with centralized resource libraries are supported.

9. Working with AI-Generated Changes 

AI responses include proposed edits. Hovering a suggestion highlights the corresponding document section for context before applying it.

10. Showing Details 

Toggle Show details to switch between: - Detailed view – shows markup for additions, deletions, and formatting. - Simplified view – clean preview of the updated text.

11. Previewing Changes 

Show in the text opens a preview window with navigation, apply/reject controls, and Track Changes conversion options. The preview stays synced with the document.

12. Applying Changes 

• Apply inserts the selected suggestion.
• Apply all accepts every AI-generated change at once.

13. Inserting Track Changes Suggestions 

With Track Changes enabled: - Insert suggestion applies individual edits as suggestions. - Suggest (under Apply all) converts all edits into Track Changes entries.

14. Rejecting Suggestions 

Use Delete (Reject) to dismiss unwanted proposals.

15. Chat History 

All conversations appear in the Chat history panel. Users can reopen sessions, rename conversations, delete entries, and filter by date or search term.

Integration 

1. Load the AIQuickActions plugin in your CKEditor configuration.
2. Add the Quick actions menu (aiQuickActions) to either the main toolbar or the balloon toolbar. Follow the toolbar configuration guide for placement details.
3. Optionally expose individual shortcuts (e.g., ask-ai, improve-writing) or entire categories such as Adjust length or Change tone for faster access.

Types of Actions 

Actions that open Chat

These push the selection into the Chat panel, optionally with a pre-filled prompt.

Examples: - ask-ai – Opens Chat with the selected text as context. - summarize – Opens Chat and auto-generates a summary request.

Actions that open a popup

These display an AI proposal in a contextual popup with Accept, Reject, and Re-run options.

Examples: - continue - make-shorter

Default Quick Actions 

Built-in actions include (grouped by category):

• ask-ai
• chat-commands
• explain
• summarize
• highlight-key-points
• improve-writing
• continue
• fix-grammar

Adjust length make-shorter, make-longer

Change tone make-tone-casual, make-tone-direct, make-tone-friendly, make-tone-confident, make-tone-professional

Translate translate-to-english, translate-to-chinese, translate-to-french, translate-to-german, translate-to-italian, translate-to-portuguese, translate-to-russian

Customization 

• Add custom actions tailored to your workflows.
• Remove unused defaults to declutter the menu.
• Reorder or re-categorize actions to match project needs.
• Place high-usage shortcuts directly on the toolbar or balloon UI.

Each Quick Action can also serve as a conversation starter with AI Chat, ensuring consistent handoff between quick transforms and deeper ideation.

Configuration 

Load the AIReviewMode plugin to enable Review Mode. Once activated, the Review Mode button appears in the AI panel, unlocking review commands and automated analysis. Refer to the AI installation guide for full setup details.

Workflow Highlights 

• Runs structured checks on grammar, style, tone, clarity, and consistency.
• Surfaces actionable suggestions in-context with accept/reject controls.
• Integrates with Track Changes to keep editorial workflows auditable.
• Provides a streamlined interface so reviewers can focus on high-impact fixes.

Usage Tips 

1. Activate Review Mode from the AI panel once the plugin is enabled.
2. Initiate an AI Review to scan the current document or selection.
3. Step through each suggestion, applying or rejecting updates inline.
4. Convert accepted edits into Track Changes suggestions when collaboration requires explicit approval trails.

For more detail, see the section on installing and enabling AI features.

Versioning 

The CKEditor Pack follows the semantic versioning model.

It uses the format:

<major>.<minor>.<patch>

• Major: Includes breaking changes
• Minor: Introduces new functionality without breaking existing setups
• Patch: Contains bug fixes and minor improvements without breaking changes

Before Updating 

Always back up your database and files before performing an update to avoid any data loss or compatibility issues.

Before proceeding with any update:

Review the changelog of all versions released since your current installation. This helps you understand new features, deprecations, or potential adjustments. You can find the full changelog in the documentation.

Run the update on a test or staging environment, if possible. This allows you to identify any conflicts or required configuration updates safely. Always create a full database and file backup before updating the extension. This ensures you can roll back quickly in case of unexpected issues.

List of versions 

Recommended: Fresh Installation 

For optimal performance and to prevent conflicts with older configurations, please consider reinstalling the entire extension.

A fresh installation ensures that all updated features, revised YAML structures and configuration changes are applied correctly.

Steps to Follow 

1. Uninstall the existing extension from the Extension Manager.
2. Clear all TYPO3 caches.
3. Install the latest version (v3.x) from TER or via Composer.
4. Verify the RTE setup in both backend and frontend.
5. Re-Configure any custom YAML settings using the updated schema included in v3.x.

Why This Is Required 

Version 3.x introduces important structural updates, new features and revised configuration logic.

A clean installation helps ensure:

• No outdated YAML files conflict with the new configuration.
• No duplicated or legacy settings remain.
• New default features load correctly.
• Overall smoother and more predictable behavior.

Requirements 

• TYPO3 v12 or v13 with composer mode enabled.
• PHP 8.1+ (matches the TYPO3 core matrix).
• Access to the extension root packages/rte_ckeditor_pack and the ability to run composer commands.

Composer Setup
