# Add block information on Field Extension plugins

[date: 2022-11-03T12:28:25.231+01:00]

A small addition to our Plugins SDK: inside the [`renderFieldExtension` hook](https://www.datocms.com/docs/plugin-sdk/field-extensions.md#renderFieldExtension), you can now access [`ctx.block`](https://github.com/datocms/plugins-sdk/blob/master/packages/sdk/src/types.ts#L1284).

If the field extension is installed in a field of a block, `ctx.block` returns the ID of the block — or `undefined` if the block is still not persisted — and the block model.
