Content Type
Tags

Separator

The separator block allows blocks or groups of blocks to be visually separated by a horizontal line.

Listing

The listing block allows the display of various listings of content. Editors can configure a number of criteria for listing content (e.g. all news from 2022 with the keyword 'research').

Introduction

The introductory block allows the display of an introductory text, which is displayed larger than normal continuous text.

Image

The image block allows images to be embedded in various display formats. Images can be displayed in different sizes (100%, L, M, S) and aligned left, right or center of the text flow.

Highlight

The highlight block allows you to highlight and tease a single piece of content. The content is displayed with a large image and a title and description in a banderole.

Heading

The heading block allows you to display headings to group multiple blocks under one topic.

Developer Reference

Schema

Pass this object inside the blocks option when calling initBridge() to register this block type with the admin UI. See Custom Blocks for the full setup guide.

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;
  }
