Lightbox

A lightbox is a type of modal that takes up the whole viewing area and dims and blurs the background content. The lightbox is typically used to display some type of slideshow of content such as images or videos.

The lightbox has three components: a header that display information about the content, a content area to display content, and a footer that provides functionality for manipulating the content

Default Lightbox Components

@wedgekit/lightbox offers default stylings for frequently used subcomponents of Lightbox. DefaultHeader, DefaultFooter, and DefaultPreviewUnavailable can be consumed like so:

import Button from '@wedgekit/button';
import Lightbox, { DefaultFooter, DefaultHeader } from '@wedgekit/lightbox';

const Example = () => {
  const [lightboxIndex, setLightboxIndex] = React.useState(0);
  const [showLightbox, setShowLightbox] = React.useState(false);

  return (
    <>
      <Button
        onClick={() => {
          setShowLightbox(true);
        }}
      >
        Open Lightbox
      </Button>
      {showLightbox && (
        <Lightbox
          footer={<DefaultFooter />}
          header={
            <DefaultHeader
              title="Lightbox Header"
              header={lightboxIndex}
              onExit={() => {
                setShowLightbox(false);
              }}
            />
          }
          index={lightboxIndex}
          label="Preview Contents"
          onChange={(index, e) => setLightboxIndex(index)}
          onExit={() => setShowLightbox(false)}
