# Introducing new `enabled_on` / `disabled_on` app blocks schema attributes (deprecating `templates`)

You can now use the new `enabled_on` / `disabled_on` app block [schema](https://shopify.dev/docs/apps/online-store/theme-app-extensions/extensions-framework#schema) attributes to specify where an app block can be used. These new attributes replace the existing `templates` attribute and work for both templates and [section groups](https://shopify.dev/themes/architecture/section-groups).

* Use the `enabled_on` attribute to limit an app block to specific templates and section groups.
* Use the `disabled_on` attribute to prevent an app block from being used in specific templates and section groups.
* These new attributes work for both app blocks and app block embeds.

Please keep in mind that you can use only one of `enabled_on` or `disabled_on`.
