Image - Light

The Image content type can be used to upload an image in various formats (JPG, GIF, PNG, SVG). The uploaded image should always have a high resolution so that it can be used flexibly, for example as a banner image. Plone automatically delivers the images in the best scaling, so there is no need to scale images down manually.

JSON Block Data

Example JSON as stored in the Plone content API. This is the data structure your component will receive in the block prop.

Component

Render component for your frontend framework. Add this to your block renderer's switch/map so it handles this @type.

function SearchBlock({ block, blockId }) {
  const [query, setQuery] = useState('');

  const facets = (block.facets || []).filter(f => !f.hidden);
  const listing = block.listing || {};
  const listingId = listing.items?.[0];
  const listingBlock = listingId ? (block.blocks?.[listingId]) : null;

  return (
    <div data-block-uid={blockId} className="search-block">
      <input
        type="search"
        placeholder="Search..."
        value={query}
        onChange={e => setQuery(e.target.value)}
      />

      {facets.length > 0 && (
        <div className="facets">
          <h4>{block.facetsTitle || 'Filter'}</h4>
          {facets.map(facet => (
            <FacetRenderer key={facet['@id']} facet={facet} />
          ))}
        </div>
      )}

      {listingBlock && (
        <ListingBlock block={listingBlock} blockId={listingId} />
      )}
    </div>
  );
}

function FacetRenderer({ facet }) {
  switch (facet.type) {
    case 'checkboxFacet':
      return <fieldset data-block-uid={facet['@id']}><legend data-edit-text="title">{facet.title}</legend>{/* checkbox options */}</fieldset>;
    case 'selectFacet':
      return <label data-block-uid={facet['@id']}><span data-edit-text="title">{facet.title}</span><select>{/* options */}</select></label>;
    case 'daterangeFacet':
      return <label data-block-uid={facet['@id']}><span data-edit-text="title">{facet.title}</span><input type="date" /> – <input type="date" /></label>;
    case 'toggleFacet':
      return <label data-block-uid={facet['@id']}><input type="checkbox" /> <span data-edit-text="title">{facet.title}</span></label>;
    default:
      return null;
  }
