# Calendar Button

This component is used to display a calendar button. When it pressed, it shows a Popover with a calendar inside.

## Usage

```jsx
import CalendarButton from 'calypso/blocks/calendar-button';

function render() {
	return <CalendarButton />;
}
```

## Props

### `children`

<table>
	<tr><td>Type</td><td>Element</td></tr>
	<tr><td>Required</td><td>No</td></tr>
</table>

### `icon`

<table>
	<tr><td>Type</td><td>String</td></tr>
	<tr><td>Required</td><td>No</td></tr>
	<tr><td>Default</td><td>calendar</td></tr>
</table>

If the component doesn't have children elements then an icon (Gridicon) will be rendered inside of this one.

### `popoverPosition`

<table>
	<tr><td>Type</td><td>String</td></tr>
	<tr><td>Required</td><td>No</td></tr>
	<tr><td>Default</td><td>bottom</td></tr>
</table>

It defines the position of the Popover once it shows. This value is propagated to the `<Popover />` instance through of the `position` property.

### `type`

<table>
	<tr><td>Type</td><td>String</td></tr>
	<tr><td>Required</td><td>Yes</td></tr>
	<tr><td>Default</td><td>button</td></tr>
</table>
