# Popup
[//]: # 'AUTO INSERT HEADER PREPUBLISH'
`lion-popup` is a component used for basic popups on click.
Its purpose is to show content appearing when the user clicks an invoker element with the cursor or with the keyboard.
## Features
- Show content when clicking the invoker
- Use the position property to position the content popup relative to the invoker
## How to use
### Installation
```sh
npm i --save @lion/popup
```
```js
import '@lion/popup/lion-popup.js';
```
### Example
```html
<lion-popup>
<div slot="content" class="tooltip">This is a popup<div>
<a slot="invoker" href="https://www.google.com/">
Popup on link
</a>
</lion-popup>
```
