@wordpress/components

Component Reference

This package includes a library of generic WordPress components to be used for creating common UI elements shared between screens and features of the WordPress dashboard.

Installation

npm install @wordpress/components --save

This package assumes that your code will run in an ES2015+ environment. If you're using an environment that has limited or no support for such language features and APIs, you should include the polyfill shipped in @wordpress/babel-preset-default in your code.

Usage

Within Gutenberg, these components can be accessed by importing from the components root directory:

/**
 * WordPress dependencies
 */
import { Button } from '@wordpress/components';

export default function MyButton() {
	return <Button>Click Me!</Button>;
}

Many components include CSS to add styles, which you will need to load in order for them to appear correctly. Within WordPress, add the wp-components stylesheet as a dependency of your plugin's stylesheet. See wp_enqueue_style documentation for how to specify dependencies.

In non-WordPress projects, link to the build-style/style.css file directly, it is located at node_modules/@wordpress/components/build-style/style.css.

Popovers and Tooltips

If you're using Popover or Tooltip components outside of the editor, make sure they are rendered within a SlotFillProvider and with a Popover.Slot somewhere up the element tree.

By default, the Popover component will render inline i.e. within its parent to which it should anchor. Depending upon the context in which the Popover is being consumed, this might lead to incorrect positioning. For example, when being nested within another popover.

This issue can be solved by rendering popovers to a specific location in the DOM via the Popover.Slot. For this to work, you will need your use of the Popover component and its Slot to be wrapped in a SlotFill provider.

A Popover is also used as the underlying mechanism to display Tooltip components. So the same considerations should be applied to them.

The following example illustrates how you can wrap a component using a Popover and have those popovers render to a single location in the DOM.

/**
 * External dependencies
 */
import { Popover, SlotFillProvider } from '@wordpress/components';

/**
 * Internal dependencies
 */
import { MyComponentWithPopover } from './my-component';

const Example = () => {
	<SlotFillProvider>
		<MyComponentWithPopover />
		<Popover.Slot />
	</SlotFillProvider>
};
