# toolbar.download

Part of [Toolbar](https://kernstra.com/docs/web-sdk/config/toolbar) in the Kernstra Web SDK 1.0.0 configuration reference.

- Type: `boolean`
- Default: `true`
- Page: https://kernstra.com/docs/web-sdk/config/toolbar/download

Show the built-in Download button. The button needs the `export` license feature. [`export.askOnDownload`](https://kernstra.com/docs/web-sdk/config/export/askondownload) says whether it asks first; [`callbacks.onDownload`](https://kernstra.com/docs/web-sdk/config/callbacks/ondownload) takes it over.

```ts
toolbar: { download: false }
```
