- * The {@glink builds/guides/overview#classic-editor classic editor} implementation.
- * It uses an inline editable and a sticky toolbar, all enclosed in a boxed UI.
- * See the {@glink examples/builds/classic-editor demo}.
- *
- * In order to create a classic editor instance, use the static
- * {@link module:editor-classic/classiceditor~ClassicEditor.create `ClassicEditor.create()`} method.
- *
- * # Classic editor and classic build
- *
- * The classic editor can be used directly from source (if you installed the
- * [`@ckeditor/ckeditor5-editor-classic`](https://www.npmjs.com/package/@ckeditor/ckeditor5-editor-classic) package)
- * but it is also available in the {@glink builds/guides/overview#classic-editor classic 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 easier customization.
- *
- * Read more about initializing the editor from source or as a build in

- * Creates a `ClassicEditor` instance.
- *
- * There are two general ways how the editor can be initialized.
- *
- * You can initialize the editor using an existing DOM element:
- *
- * ClassicEditor
- * .create( document.querySelector( '#editor' ) )
- * .then( editor => {
- * console.log( 'Editor was initialized', editor );
- * } )
- * .catch( err => {
- * console.error( err.stack );
- * } );
- *
- * The element's content will be used as the editor data and the element will be replaced by the editable element and the editor UI.
- *
- * Alternatively, you can initialize the editor by passing the initial data directly as a `String`.
- * In this case, the editor will render an element that must be inserted into the DOM for the editor to work properly:
- *
- * ClassicEditor
- * .create( '<p>Hello world!</p>' )
- * .then( editor => {
- * console.log( 'Editor was initialized', editor );
- *
- * // 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.
- *
- * You can also mix those two ways by providing a DOM element to be used and passing the initial data through the config:
- *
- * ClassicEditor
- * .create( document.querySelector( '#editor' ), {
- * initialData: '<h2>Initial data</h2><p>Foo bar.</p>'
- * } )
- * .then( editor => {
- * console.log( 'Editor was initialized', editor );
- * } )
- * .catch( err => {
- * console.error( err.stack );
- * } );
- *
- * This method can be used to initialize the editor on an existing element with 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 initial data both as the first parameter and also in the config.
- *
- * See also the {@link module:core/editor/editorconfig~EditorConfig editor configuration documentation} to learn more about
- * customizing plugins, toolbar and other.
- *
- * @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
- * and the {@link module:editor-classic/classiceditorui~ClassicEditorUI#element editor element} will replace the passed element
- * in the DOM (the original one will be hidden and the editor will be injected next to it).
- *
- * Moreover, the editor data will be set back to the original element once the editor is destroyed and when a form, in which
- * this element is contained, is submitted (if the original element is a `<textarea>`). This ensures seamless integration with native
- * web forms.
- *
- * 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 {@link module:editor-classic/classiceditorui~ClassicEditorUI#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.
