# Overlays System
[//]: # 'AUTO INSERT HEADER PREPUBLISH'
Supports different types of overlays like dialogs, toasts, tooltips, dropdown, etc...
Manages their position on the screen relative to other elements, including other overlays.
## Features
- [**Overlays Manager**](./docs/OverlaysManager.md), a global repository keeping track of all different types of overlays.
- [**Overlays System: Scope**](./docs/OverlaySystemScope.md), outline of all possible occurrences of overlays. Divided into two main types:
- [**Global Overlay Controller**](./docs/GlobalOverlayController.md), controller for overlays relative to the viewport.
- [**Local Overlay Controller**](./docs/LocalOverlayController.md), controller for overlays positioned next to invokers they are related to.
## How to use
### Installation
```sh
npm i --save @lion/overlays
```
### Example
```js
import { overlays } from '@lion/overlays';
const myCtrl = overlays.add(
new OverlayTypeController({
/* options */
}),
);
// name OverlayTypeController is for illustration purpose only
// please read below about existing classes for different types of overlays
```
## Rationals
- No `aria-controls`: as support for it is not quite there yet
- No `aria-haspopup` People knowing the haspop up and hear about it dont expect a dialog to open (at this moment in time) but expect a sub-menu. Until support for the dialog value has better implementation, its probably best to not use aria-haspopup on the element that opens the modal dialog.
