This extension provides placeholder support. Give your users an idea what they should write with a tiny hint. There is a handful of things to customize, if you feel like it.

## Installation
```bash
# with npm
npm install @tiptap/extension-placeholder

# with Yarn
yarn add @tiptap/extension-placeholder
```

## Settings

### emptyEditorClass
The added CSS class if the editor is empty.

Default: `'is-editor-empty'`

Placeholder.configure({
  emptyEditorClass: 'is-editor-empty',
})
```

You can even use a function to add placeholder depending on the node:

Placeholder.configure({
  placeholder: ({ node }) => {
    if (node.type.name === 'heading') {
      return 'What’s the title?'
    }

    return 'Can you add some further context?'
  },
})
```

Default: `true`

```js
Placeholder.configure({
  showOnlyWhenEditable: false,
})
```

### showOnlyCurrent

Default: `true`

```js
Placeholder.configure({
  showOnlyCurrent: false
})
```
