# Placeholder
[![Version](https://img.shields.io/npm/v/@tiptap/extension-placeholder.svg?label=version)](https://www.npmjs.com/package/@tiptap/extension-placeholder)
[![Downloads](https://img.shields.io/npm/dm/@tiptap/extension-placeholder.svg)](https://npmcharts.com/compare/@tiptap/extension-placeholder?minimal=true)
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
npm install @tiptap/extension-placeholder
```
### Additional Setup
Placeholders are displayed with the help of CSS.
**Display a Placeholder only for the first line in an empty editor.**
```
.tiptap p.is-editor-empty:first-child::before {
color: #adb5bd;
content: attr(data-placeholder);
float: left;
height: 0;
pointer-events: none;
}
```
**Display Placeholders on every new line.**
```
.tiptap p.is-empty::before {
color: #adb5bd;
content: attr(data-placeholder);
float: left;
height: 0;
pointer-events: none;
}
```
## Settings
### emptyEditorClass
The added CSS class if the editor is empty.
Default: `'is-editor-empty'`
```js
Placeholder.configure({
emptyEditorClass: 'is-editor-empty',
})
```
### emptyNodeClass
The added CSS class if the node is empty.
Default: `'is-empty'`
```js
Placeholder.configure({

```
You can even use a function to add placeholder depending on the node:
```js
Placeholder.configure({
placeholder: ({ node }) => {
if (node.type.name === 'heading') {
return 'Whats the title?'
}
return 'Can you add some further context?'
},
})
```
### showOnlyWhenEditable

Default: `true`
```js
Placeholder.configure({
showOnlyWhenEditable: false,
})
```
### showOnlyCurrent
Show decorations only in currently selected node.
Default: `true`
```js
Placeholder.configure({
showOnlyCurrent: false
})
```
### includeChildren
Show decorations also for nested nodes.
Default: `false`
```js
Placeholder.configure({
includeChildren: true
})
```
