|
| 29 | * ```ts
|
| 30 | * const headingConfig = {
|
| 31 | * options: [
|
| 32 | * { model: 'paragraph', title: 'Paragraph', class: 'ck-heading_paragraph' },

|
| 38 | * ```
|
| 39 | *
|
| 40 | * It defines 3 levels of headings. In the editor model they will use `heading1`, `heading2`, and `heading3` elements.
|
| 41 | * Their respective view elements (so the elements output by the editor) will be: `h2`, `h3`, and `h4`. This means that
|
| 42 | * if you choose "Heading 1" in the headings dropdown the editor will turn the current block to `<heading1>` in the model
|
| 43 | * which will result in rendering (and outputting to data) the `<h2>` element.
|
| 44 | *
|
| 45 | * The `title` and `class` properties will be used by the `headings` dropdown to render available options.
|
| 46 | * Usually, the first option in the headings dropdown is the "Paragraph" option, hence it's also defined on the list.
|
| 47 | * However, you don't need to define its view representation because it's handled by
|
| 48 | * the {@link module:paragraph/paragraph~Paragraph} feature (which is required by
|
| 49 | * the {@link module:heading/headingediting~HeadingEditing} feature).
|
| 50 | *
|
| 51 | * You can **read more** about configuring heading levels and **see more examples** in
|
| 52 | * the {@glink features/headings Headings} guide.
|
| 53 | *
|
| 54 | * Note: In the model you should always start from `heading1`, regardless of how the headings are represented in the view.
|
| 55 | * That's assumption is used by features like {@link module:autoformat/autoformat~Autoformat} to know which element
|
| 56 | * they should use when applying the first level heading.
|
| 57 | *
|
| 58 | * The defined headings are also available as values passed to the `'heading'` command under their model names.
|
| 59 | * For example, the below code will apply `<heading1>` to the current selection:
|
| 60 | *
|
| 61 | * ```ts
|
| 62 | * editor.execute( 'heading', { value: 'heading1' } );
|
| 63 | * ```
