Add Custom Editor
Before you begin…
This tutorial goes through the process of adding CKEditor4 as an editor that can be used by the WYSIWYG UI component.
As a developer, use this tutorial as a guide for adding your own custom JavaScript editor to Magento.
Step 1. Make the editor library available
Download and install your editor’s library into your module’s view/base/web/js
directory to have Magento publish it under pub/static
.
Step 2. Register editor
In your module’s etc/adminhtml/di.xml
file, add your editor to the list of adapterOptions
to include it to the list of available WYSIWYG editors in the Admin.
Provide unique values for the name
parameter and the value
and label
entries for your editor to avoid naming collisions.
If you are also extending or overriding the configuration for Variable, Widget, or Gallery, you must use the same string as the value
entry.

<type name="Magento\Cms\Model\Config\Source\Wysiwyg\Editor">
<arguments>
<argument name="adapterOptions" xsi:type="array">
<item name="ckeditor" xsi:type="array">
<item name="value" xsi:type="string">CKEditor_CKEditor4/ckeditor4Adapter</item>
<item name="label" xsi:type="string" translatable="true">ckeditor</item>
</item>
</argument>
</arguments>
</type>
To avoid issues in the case that we remove or disable the adapter module, add this configuration to the di.xml
file:

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<type name="Magento\Ui\Block\Wysiwyg\ActiveEditor">
<arguments>
<argument name="availableAdapterPaths" xsi:type="array">
<item name="CKEditor_CKEditor4/ckeditor4Adapter" xsi:type="string"/>
</argument>
</arguments>
</type>
</config>
Step 3. Create editor adapter
Create an adapter for your editor in your module’s view/base/web
directory.
This adapter should implement the extensions points called by wysiwygInstance
in the following file:
lib/mage/adminhtml/wysiwyg/tiny_mce/setup.js
At minimum your adapter should implement the following methods:
getAdapterPrototype()
setup( mode )
openFileBrowser( o )
toggle()
onFormValidation()
encodeContent(content)
If you are integrating Magento entities such as variable and widget as plugins, your adapter must also implement the following methods:
get( id )
- returns the editor by it element idgetContent()
- returns the content stored in the WYSIWYG fieldsetContent(content)
- replaces the entire contents of the WYSIWYG with the string content parameterinsertContent( content )
- inserts content into the editorsetCaretOnElement( targetElement )
- sets the caret location in the editor-
activeEditor()
- returns the active editor as an object with aselection
property.The
selection
property returns an instance of the editor with the following additional methods defined:-
getBookmark( type:Number, normalized:Boolean ):Object
- returns a bookmark object that has the location for the current selection.This is used to restore the selection after content modification in the document.
moveToBookmark( bookmark:Object ):Boolean
- restores the selection of the specified bookmark.getNode():Element
- returns the currently selected element or common ancestor element for both start and end of the selection.-
select( targetElement )
- selects the specified element.This places the start and end of the selection range around the element.
collapse( to_start:Boolean ):void
- collapse the selection to start or end of range.

Step 4. Load editor library
After loading, modifying, and merging all configurations, Magento serializes the result into a JSON object and passes it to the UI component.
In your module’s view/base/requirejs-config.php
file, add a shim configuration entry for your editor in order to have RequireJS load it correctly.
Example: CKEditor\CKEditor4\view\base\requirejs-config.php

var config = {
"shim": {
"CKEditor_CKEditor4/js/ckeditor4/ckeditor": { "exports": "CKEDITOR" }
}
};
