-# Quill WYSIWYG Pimcore Bundle
-This bundle provides the [Quill 2.x](https://quilljs.com/) WYSIWYG editor integration for Pimcore.
-This includes the WYSIWYG for Documents, Data Objects and Shared Translations.
+---
+title: Quill WYSIWYG Editor
+---
-## Installation
-See [Installation](./doc/00_Installation/README.md)
+# Quill WYSIWYG Editor
-## Migration to Quill
-See [Migration](./doc/01_Migration_to_Quill.md)
+Integrates the [Quill 2.x](https://quilljs.com/) WYSIWYG editor into Pimcore.
+Quill provides rich-text editing for documents, data objects, and shared translations.
-## Configuration
+## Features
-Available configuration options can be found here: [config options](https://quilljs.com/docs/configuration/)
+- Rich-text editing based on [Quill 2.x](https://quilljs.com/) with built-in
+ undo/redo and HTML source editing
+- WYSIWYG support for document editables, data object fields, and shared translations
+- Per-field toolbar configuration through Twig editables
+- Global editor defaults through Symfony configuration (`pimcore_studio_ui`)
-### Themes
+## Documentation Overview
-Available themes and how to configure it can be found here: [themes](https://quilljs.com/docs/customization/themes)
-
-## Examples
-
-### Basic usage
-
-`wysiwyg` helper doesn't require any additional configuration options.
-The following code customize the toolbar.
-
-```twig
-
- {{ pimcore_wysiwyg("specialContent", {
- modules: {
- toolbar: {
- container: [
- [{ header: [1, 2, 3, 4, 5, 6, false] }]
- ]
- }
- }
- })
- }}
-
-```
-
-### Custom configuration for Quill
-
-A list of configuration options you can find in the [Quill toolbar documentation](https://quilljs.com/docs/modules/toolbar).
-In addition to this you can also configure `undo`, `redo` and `html-edit`.
-
-The WYSIWYG editable allows us to specify the toolbar.
-If you have to limit styling options (for example only basic styles like `` tag and lists would be allowed), just use `toolbar` option.
-
-```twig
-
- {{ pimcore_wysiwyg("specialContent", {
- modules: {
- toolbar: {
- container: [
- ['undo', 'redo'],
- [{ header: [1, 2, 3, 4, 5, 6, false] }],
- ['html-edit']
- ]
- }
- }
- })
- }}
-
-```
-
-Now the user can use only the limited toolbar.

-# Migration to Quill
-
-Every WYSIWYG-Editor (TinyMCE, CKEditor, ...) has its own peculiarities, that means that they are never 100% compatible to each other. Potential incompatibilities can result into different markup or styling, in rare edge-cases even in a kind of data-loss if the existing markup is not supported by Quill. Therefore it's important to check your existing contents for compatibility with the editor.
-
-## Replace TinyMCE with Quill
-
-First install Quill: [Installation](./00_Installation/README.md)
-
-### Bundles
-
-Make sure TinyMCE isn't enabled in the `config/bundles.php` file. The following lines should be removed:
-
-```php
-use Pimcore\Bundle\TinymceBundle\PimcoreTinymceBundle;
-// ...
-
-return [
- // ...
- PimcoreTinymceBundle::class => ['all' => true],
- // ...
-];
-```
-
-## Known incompatibilities
-
-### Configuration
-
-Change the twig and public configs according to [config options](https://quilljs.com/docs/configuration/)
-
-### Tables & Lists
-
-Tables & Lists form TinyMCE could be displayed different in Quill than in TinyMCE. Please check your fields after migration.

+
+# Configuration
+
+The Quill editor supports configuration through Pimcore editables (per-field) and
+Symfony configuration (global defaults).
+
+## Default Toolbar
+
+When no custom toolbar is configured, the editor uses this default:
+
+```
+undo, redo | H1-H6 headings | bold, italic | alignment |
+ordered list, bullet list | indent, outdent | blockquote |
+link, table | clean, html-edit
+```
+
+## Toolbar Configuration in Twig
+
+The `pimcore_wysiwyg` editable accepts Quill configuration options directly.
+Use the `modules.toolbar.container` array to define which toolbar controls are available.
+
+### Basic example
+
+```twig
+{{ pimcore_wysiwyg("content", {
+ modules: {
+ toolbar: {
+ container: [
+ [{ header: [1, 2, 3, 4, 5, 6, false] }]
+ ]
+ }
+ }
+ })
+}}
+```
+
+### Toolbar with undo, redo, and HTML editing
+
+In addition to [standard Quill toolbar options](https://quilljs.com/docs/modules/toolbar),
+the bundle provides `undo`, `redo`, and `html-edit` controls.
+
+```twig
+{{ pimcore_wysiwyg("content", {
+ modules: {
+ toolbar: {
+ container: [
+ ['undo', 'redo'],
+ [{ header: [1, 2, 3, 4, 5, 6, false] }],
+ ['html-edit']
+ ]
+ }
+ }
+ })
+}}
+```
+
+Controls not listed in the `container` array are excluded from the toolbar.
+
+## Global Configuration
+
+Global WYSIWYG defaults are configured under the `pimcore_studio_ui` extension
+provided by the Studio UI bundle. The Quill bundle does not define its own
+configuration namespace.
+
+These defaults apply to all WYSIWYG fields unless overridden per-field in Twig.
+
+```yaml
+# config/packages/pimcore_studio_ui.yaml
+pimcore_studio_ui:
+ wysiwyg:
+ defaultEditorConfig:
+ dataObject:
+ modules:
+ toolbar:
+ container:
+ - [{ header: [1, 2, 3, 4, 5, 6, false] }]
+ document:
+ modules:
+ toolbar:
+ container:
+ - [{ header: [1, 2, 3, 4, 5, 6, false] }]
+```
+
+- `dataObject` - applies to WYSIWYG fields in data object classes
+- `document` - applies to WYSIWYG editables in documents
+- Per-field configuration in Twig overrides these global defaults
+- Shared translations use the Quill editor but do not have a separate global config key
+
+:::note
+The configuration structure under `dataObject` and `document` follows the
+[Quill configuration format](https://quilljs.com/docs/configuration/).
+:::
+
+## Themes
+
+Quill supports multiple themes that control the editor's appearance.
+Set the theme in the Quill configuration options:
+
+```twig
+{{ pimcore_wysiwyg("content", {
+ theme: "snow"
+ })
+}}
+```
+
+See the [Quill themes documentation](https://quilljs.com/docs/customization/themes)
+for available themes.

-##### Global Configuration (only for admin-ui-classic-bundle)
-
-You can add a Global Configuration for all WYSIWYG Editors for all documents by setting `pimcore.document.editables.wysiwyg.defaultEditorConfig`.
-You can add a Global Configuration for all WYSIWYG Editors for all data objects by setting `pimcore.object.tags.wysiwyg.defaultEditorConfig`.
-
-For this purpose, you can create a [Pimcore Bundle](https://pimcore.com/docs/pimcore/current/Development_Documentation/Extending_Pimcore/Bundle_Developers_Guide/index.html) and add the
-configuration in a file in the `Resources/public` directory of your bundle (e.g. `Resources/public/js/editmode.js`).
-
-```
-pimcore.document.editables.wysiwyg = pimcore.document.editables.wysiwyg || {};
-pimcore.document.editables.wysiwyg.defaultEditorConfig = { menubar: true };
-```
-This will show you the default menubar from Quill in all document editables.
-
-For the data object settings, you should put them in the `startup.js` in your bundle.
-```
-pimcore.registerNS("pimcore.plugin.YourQuillEditorConfigBundle");
-
-pimcore.plugin.YourQuillEditorConfigBundle = Class.create({
-
- initialize: function () {
- document.addEventListener(pimcore.events.pimcoreReady, this.pimcoreReady.bind(this));

- }
-});
-
-const YourQuillEditorConfigBundlePlugin = new pimcore.plugin.YourQuillEditorConfigBundle();
-```
-
-
-
-To load the `editmode.js` file in editmode, you need to implement `getEditmodeJsPaths` in your bundle class. Given your bundle is named
-`AppAdminBundle` and your `editmode.js` and `startup.js` created before was saved to `src/AppAdminBundle/public/js/editmode.js` and `src/AppAdminBundle/public/js/startup.js`:
-
-```php
- 'onEditmodeJsPaths'
- ];
- }
-
- public function onEditmodeJsPaths(PathsEvent $event): void
- {
- $event->addPaths([
- '/bundles/app/js/pimcore/editmode.js'
- ]);

+
+# Migration from TinyMCE
+
+Every WYSIWYG editor (TinyMCE, CKEditor, etc.) produces different markup.
+Migrating between editors can result in different styling or formatting,
+and in rare cases content that the new editor does not support.
+Review existing content for compatibility after switching.
+
+## Replace TinyMCE with Quill
+
+1. Install the Quill bundle - see [Installation](./00_Installation/README.md)
+
+2. Remove TinyMCE:
+
+ ```bash
+ composer remove pimcore/tinymce-bundle
+ ```
+
+ This also removes it from `config/bundles.php` if Symfony Flex is active.
+ Otherwise, manually remove the bundle registration:
+
+ ```php
+ // Remove these lines from config/bundles.php:
+ use Pimcore\Bundle\TinymceBundle\PimcoreTinymceBundle;
+
+ return [
+ // Remove:
+ PimcoreTinymceBundle::class => ['all' => true],
+ ];
+ ```
+
+3. Update Twig templates and configuration files to use Quill options instead
+ of TinyMCE-specific settings. See [Configuration](./02_Configuration.md) for
+ toolbar options and global defaults.
+
+## Known Incompatibilities
+
+### Tables and Lists
+
+Quill renders TinyMCE tables and lists differently.
+Check all WYSIWYG fields that contain tables or lists after migration.
