# HTML Sheet Element

HTML Custom Element for creating sheets. Displayed as a bottom sheet on mobile and a centered sheet on desktop.


## Features

- There is a handle at the top of the sheet that can be used to open or close the sheet
- The sheet can be closed using a button in the sheet header, using the `Esc` key, or by clicking outside the bottom sheet
    - This behavior is configurable. You can turn off the `Esc` or the click outside the sheet when you want.
- API is similar to the `<dialog>` element's
    - Supports forms inside of it
    - Uses familiar method names and the same event names
- There are many customization options


## Installation

You can install this library from the npm registry:

```bash
npm install @ivteplo/html-sheet-element
```

Or you can import it dynamically from a CDN:

```javascript
const { SheetElement } = await import("https://unpkg.com/@ivteplo/html-sheet-element@1.0.0/build/index.js")
```


## Usage

Before being able to use the element in your HTML, you need to specify a tag name for it using JavaScript:

```javascript
import { SheetElement } from "@ivteplo/html-sheet-element"

// You can choose another tag name instead of `ui-sheet`
SheetElement.defineAs("ui-sheet")
```

Then you can use the tag in your HTML:

```html
<ui-sheet id="sheet">
  <p>Hello World!</p>
</ui-sheet>
```

To open a sheet, call the element's `showModal` method:

```javascript
const sheet = document.querySelector("ui-sheet")
sheet.showModal()
```
