# URLPopover

URLPopover is a presentational React component used to render a popover used for editing and viewing a url.

## Setup

The component will be rendered adjacent to its parent.

```jsx
import { ToggleControl, Button } from '@wordpress/components';
import { URLPopover } from '@wordpress/block-editor';
import { keyboardReturn } from '@wordpress/icons';

class MyURLPopover extends Component {
	constructor() {
		super( ...arguments );

		this.onChangeURL = this.onChangeURL.bind( this );
		this.openURLPopover = this.openURLPopover.bind( this );
		this.closeURLPopover = this.closeURLPopover.bind( this );
		this.submitURL = this.submitURL.bind( this );
		this.setTarget = this.setTarget.bind( this );

		this.state = {
			isVisible: false,
		};
	}

	onChangeURL( url ) {
		this.setState( { url } );
	}

	openURLPopover() {
		this.setState( {
			isVisible: true,
		} );
	}

	closeURLPopover() {
		this.setState( {
			isVisible: false,
		} );
	}

	submitURL() {
		// Not shown: Store the updated url.

		this.closeURLPopover();
	}

	setTarget() {
		// Not shown: Store the updated 'opensInNewWindow' setting.
	}

	render() {
		const { opensInNewWindow } = this.props;
		const { url, isVisible, isEditing } = this.state;

		return (
			<>
				<Button onClick={ this.openURLPopover }>Edit URL</Button>
				{ isVisible && (
					<URLPopover
						onClose={ this.closeURLPopover }
						renderSettings={ () => (
							<ToggleControl
								label={ __( 'Open in new tab' ) }
								checked={ opensInNewWindow }
								onChange={ this.setTarget }
							/>
						) }
					>
						<form onSubmit={ this.submitURL }>
							<input
								type="url"
								value={ url }
								onChange={ this.onChangeURL }
							/>
							<Button
								icon={ keyboardReturn }
								label={ __( 'Apply' ) }
								type="submit"
							/>
						</form>
					</URLPopover>
				) }
			</>
		);
	}
}
```

## Props

The component accepts the following props. Any other props are passed through to the underlying `Popover` component ([refer to props documentation](/packages/components/src/popover/README.md)).

### placement

Where the Popover should be positioned relative to its parent. Defaults to "bottom".

-   Type: `String`

an element.

is provided, a toggle button will be rendered in the popover that allows the user to open and close the settings
drawer.

## Useful UI pieces

The URLPopover exposes two components that may be used as child components to make the UI creation process easier.
Although in the editor these components are used inside URLPopover and they were built with URLPopover use cases in mind, it maybe is possible and perfectly fine to use them standalone if they fit a use-case.

The component accepts the following props. Any other props are passed through to the underlying `div` container.

If no className is passed only "block-editor-url-popover**link-viewer" is used.
