}Rendering
How this block renders in your frontend. Add its handling to your renderer, or — for list-style blocks — register a fetcher and reuse your list rendering.
function AccordionBlock({ block }) {
const panels = block.panels || [];
return (
<div data-block-uid={block['@uid']} className="accordion-block">
{panels.map(panel => {
const panelId = panel['@id'];
return <AccordionPanel key={panelId} panel={panel} panelId={panelId} />;
})}
</div>
);
}
function AccordionPanel({ panel, panelId }) {
const [open, setOpen] = useState(!panel.collapsed);
const contentBlocks = panel.blocks || {};
const contentLayout = panel.blocks_layout?.items || [];
return (
<div data-block-uid={panelId} className="accordion-panel">
<button onClick={() => setOpen(!open)} className="accordion-header">
<span data-edit-text="title">{panel.title}</span>
<span>{open ? '▲' : '▼'}</span>
</button>
{open && (
<div className="accordion-content">
{contentLayout.map(id => (
<BlockRenderer key={id} block={{ ...contentBlocks[id], '@uid': id }} />
))}
</div>
)}
</div>
);
