# Feature: #102836 - Allow deleting IRRE elements via `postMessage()` {#feature-102836-1705994823}

See [forge#102836](https://forge.typo3.org/issues/102836)

## Description {#description}

To invoke a deletion on items in FormEngine's Inline Relation container
API-wise, a new message identifier `typo3:foreignRelation:delete` has been
introduced.

Example usage:

```js
import { MessageUtility } from '@typo3/backend/utility/message-utility.js';

MessageUtility.send({
    actionName: 'typo3:foreignRelation:delete',
    objectGroup: 'data-<page_id>-<parent_table>-<parent_uid>-<reference_table>',
    uid: '<reference_uid>'
});
```

## Impact {#impact}

Extension developers are now able to trigger the deletion of IRRE elements via
API.
