The multi-root editor type is an editor type that features multiple, separate editable areas.
Try all premium features – no credit card needed.
The main difference between using a multi-root editor and using multiple separate editors (like in the inline editor demo) is the fact that in a multi-root editor all editable areas belong to the same editor instance share the same configuration, toolbar and the undo stack, and produce one document.
The capital city of Malta is the top destination this summer. It’s home to cutting-edge contemporary architecture, baroque masterpieces, delicious local cuisine, and at least 8 months of sun. It’s also a top destination for filmmakers, so you can take a tour through locations familiar to you from Game of Thrones, Gladiator, Troy, and many more.
Check out the Editor types guide to learn more about implementing this kind of editor. You will find implementation steps there. You can see this example editor’s code below.
import {
MultiRootEditor,
Essentials,
Bold,
Italic,
Heading,
Link,
Table,
MediaEmbed,
List,
Indent
} from 'ckeditor5';
import 'ckeditor5/ckeditor5.css';

content: document.querySelector( '#content' ),

.then( editor => {
window.editor = editor;
// Append toolbar to a proper container.
const toolbarContainer = document.querySelector( '#toolbar' );
toolbarContainer.appendChild( editor.ui.view.toolbar.element );
// Make toolbar sticky when the editor is focused.
editor.ui.focusTracker.on( 'change:isFocused', () => {
if ( editor.ui.focusTracker.isFocused ) {
toolbarContainer.classList.add( 'sticky' );
} else {
toolbarContainer.classList.remove( 'sticky' );
}
} );
} )
.catch( error => {
console.error( 'There was a problem initializing the editor.', error );
} );

Wrapping the structure inside a pair of

using arrow keys at the start and end of an editable area.
You can skip them if you don't want to move the
caret between editable areas using arrow keys.

Please note that setting and reading the editor data is different for multi-root editor.
Setting the data using editor.setData():
editor.setData( {
header: '<p>Content for header part.</p>',
content: '<p>Content for main part.</p>',
leftSide: '<p>Content for left-side box.</p>',
rightSide: '<p>Content for right-side box.</p>'
} );
Setting the data through config.initialData:
MultiRootEditor.create(
{
header: document.querySelector( '#header' ),
content: document.querySelector( '#content' ),
leftSide: document.querySelector( '#left-side' ),
rightSide: document.querySelector( '#right-side' )
},
{
initialData: {
header: '<p>Content for header part.</p>',
content: '<p>Content for main part.</p>',
leftSide: '<p>Content for left-side box.</p>',
rightSide: '<p>Content for right-side box.</p>'
}
}
);
editor.getData( { rootName: 'leftSide' } ); // -> '<p>Content for left-side box.</p>'
