## ToggleButton

`<ToggleButton checked="checked" @onchange={{action 'change'}} as |api|>Toggle</ToggleButton>`

`<ToggleButton />` is a straightforward combination of a `<label>` and `<input type="checkbox" />` to allow you to easily setup CSS based (`input:checked ~ *`) visual toggling. The body of the component ends up inside the `<label>`.

Additionally, a `clickoutside` is currently included, so if the toggle is in an 'on' state, clicking outside the `<ToggleButton>` itself will un-toggle the component. This could be changed in a future version for this to be configurable/preventable and/or use/rely on a modifer instead.

### Arguments

| Argument/Attribute | Type | Default | Description |
| --- | --- | --- | --- |
| `checked` | `Boolean` | false | The default value of the toggle on/off (true/false) |
| `onchange` | `Function` |  | The action to fire when the data changes. Emits an Event-like object with a `target` that is a reference to the underlying standard DOM input element. |

### Methods/Actions/api

| Method/Action |  Description |
| --- | --- |
| `click` | Fire a click event on the ToggleButton/input which reverse the state of the toggle. |

### Example

Here is an example of a simple CSS based dropdown menu. Note: The general sibling selector (`~`) should be used as the label/button itself is the adjacent sibling (`+`).

```handlebars
<div class="menu">
  <ToggleButton>
	  Open Menu
  </ToggleButton>
  <ul>
    <li><a href="">Link 1</a></li>
    <li><a href="">Link 2</a></li>
  </ul>
</div>
```

```css
.menu input ~ ul {
  display: none;
}
.menu input:checked ~ ul {
  display: block;
}
```
