- * The {@glink builds/guides/overview#document-editor decoupled editor} implementation.
- * It provides an inline editable and a toolbar. However, unlike other editors,
- * it does not render these components anywhere in the DOM unless configured.
- *
- * This type of an editor is dedicated to integrations which require a customized UI with an open
- * structure, allowing developers to specify the exact location of the interface.
- *
- * See the document editor {@glink examples/builds/document-editor demo} to learn about possible use cases
- * for the decoupled editor.
- *
- * In order to create a decoupled editor instance, use the static
- * {@link module:editor-decoupled/decouplededitor~DecoupledEditor.create `DecoupledEditor.create()`} method.
- *
- * # Decoupled editor and document editor build
- *
- * The decoupled editor can be used directly from source (if you installed the
- * [`@ckeditor/ckeditor5-editor-decoupled`](https://www.npmjs.com/package/@ckeditor/ckeditor5-editor-decoupled) package)
- * but it is also available in the {@glink builds/guides/overview#document-editor document editor build}.
- *
- * {@glink builds/guides/overview Builds} are ready-to-use editors with plugins bundled in. When using the editor from
- * source you need to take care of loading all plugins by yourself
- * (through the {@link module:core/editor/editorconfig~EditorConfig#plugins `config.plugins`} option).
- * Using the editor from source gives much better flexibility and allows for easier customization.
- *
- * Read more about initializing the editor from source or as a build in
- * {@link module:editor-decoupled/decouplededitor~DecoupledEditor.create `DecoupledEditor.create()`}.

- /**
- * Creates a new decoupled editor instance.
- *
- * Remember that `DecoupledEditor` does not append the toolbar element to your web page so you have to do it manually after the editor
- * has been initialized.
- *
- * There are two ways how the editor can be initialized.
- *
- * # Using an existing DOM element (and loading data from it)
- *
- * You can initialize the editor using an existing DOM element:
- *
- * DecoupledEditor
- * .create( document.querySelector( '#editor' ) )
- * .then( editor => {
- * console.log( 'Editor was initialized', editor );
- *
- * // Append the toolbar to the <body> element.
- * document.body.appendChild( editor.ui.view.toolbar.element );
- * } )
- * .catch( err => {
- * console.error( err.stack );
- * } );
- *
- * The element's content will be used as the editor data and the element will become the editable element.
- *
- * # Creating a detached editor
- *
- * Alternatively, you can initialize the editor by passing the initial data directly as a string.
- * In this case, you will have to manually append both the toolbar element and the editable element to your web page.
- *
- * DecoupledEditor
- * .create( '<p>Hello world!</p>' )
- * .then( editor => {
- * console.log( 'Editor was initialized', editor );
- *
- * // Append the toolbar to the <body> element.
- * document.body.appendChild( editor.ui.view.toolbar.element );
- *
- * // Initial data was provided so the editor UI element needs to be added manually to the DOM.
- * document.body.appendChild( editor.ui.element );
- * } )
- * .catch( err => {
- * console.error( err.stack );
- * } );
- *
- * This lets you dynamically append the editor to your web page whenever it is convenient for you. You may use this method if your
- * web page content is generated on the client side and the DOM structure is not ready at the moment when you initialize the editor.
- *
- * # Using an existing DOM element (and data provided in `config.initialData`)
- *
- * You can also mix these two ways by providing a DOM element to be used and passing the initial data through the configuration:
- *
- * DecoupledEditor
- * .create( document.querySelector( '#editor' ), {
- * initialData: '<h2>Initial data</h2><p>Foo bar.</p>'
- * } )
- * .then( editor => {
- * console.log( 'Editor was initialized', editor );
- *
- * // Append the toolbar to the <body> element.
- * document.body.appendChild( editor.ui.view.toolbar.element );
- * } )
- * .catch( err => {
- * console.error( err.stack );
- * } );
- *
- * This method can be used to initialize the editor on an existing element with the specified content in case if your integration
- * makes it difficult to set the content of the source element.
- *
- * Note that an error will be thrown if you pass the initial data both as the first parameter and also in the configuration.
- *
- * # Configuring the editor
- *
- * See the {@link module:core/editor/editorconfig~EditorConfig editor configuration documentation} to learn more about
- * customizing plugins, toolbar and more.
- *
- * # Using the editor from source
- *
- * The code samples listed in the previous sections of this documentation assume that you are using an
- * {@glink builds/guides/overview editor build} (for example – `@ckeditor/ckeditor5-build-decoupled`).
- *
- * If you want to use the decoupled editor from source (`@ckeditor/ckeditor5-editor-decoupled/src/decouplededitor`),
- * you need to define the list of
- * {@link module:core/editor/editorconfig~EditorConfig#plugins plugins to be initialized} and
- * {@link module:core/editor/editorconfig~EditorConfig#toolbar toolbar items}. Read more about using the editor from
- * source in the {@glink builds/guides/integration/advanced-setup "Advanced setup" guide}.
- *
- * @param {HTMLElement|String} sourceElementOrData The DOM element that will be the source for the created editor
- * or the editor's initial data.
- *
- * If a DOM element is passed, its content will be automatically loaded to the editor upon initialization.
- * Moreover, the editor data will be set back to the original element once the editor is destroyed.
- *
- * If the initial data is passed, a detached editor will be created. In this case you need to insert it into the DOM manually.
- * It is available under the {@link module:editor-decoupled/decouplededitorui~DecoupledEditorUI#element `editor.ui.element`} property.
- *
- * @param {module:core/editor/editorconfig~EditorConfig} [config] The editor configuration.
- * @returns {Promise} A promise resolved once the editor is ready. The promise resolves with the created editor instance.
