A breadcrumb displays the current location within a hierarchy. It allows going back to states higher up in the hierarchy.
## When To Use
- When the system has more than two layers in a hierarchy.
- When you need to inform the user of where they are.
- When the user may need to navigate back to a higher level.
```jsx
// works when >=5.3.0, recommended ✅
return <Breadcrumb items={[{ title: 'sample' }]} />;
// works when <5.3.0, deprecated when >=5.3.0 🙅🏻‍♀️
return (
<Breadcrumb>
<Breadcrumb.Item>sample</Breadcrumb.Item>
</Breadcrumb>
);
// or
return <Breadcrumb routes={[{ breadcrumbName: 'sample' }]} />;
```

},
],

];
function itemRender(route, params, items, paths) {
const last = items.indexOf(item) === items.length - 1;
return last ? <span>{item.title}</span> : <Link to={paths.join('/')}>{item.title}</Link>;
}
return <Breadcrumb itemRender={itemRender} items={items} />;
```
