# Theme app extensions now support conditional app blocks

The visibility of an app block, or app embed block, of a [theme app extension](https://shopify.dev/apps/online-store/theme-app-extensions/) can now be controlled based on a custom condition.

The condition can be included in the block's [schema](https://shopify.dev/apps/online-store/theme-app-extensions/extensions-framework#schema) with the `available_if` attribute, and the state of the condition is stored in an [app-owned metafield](https://shopify.dev/api/admin-graphql/2022-04/enums/MetafieldOwnerType#value-apipermission). The metafield can be accessed through the Liquid [`app` object](https://shopify.dev/api/liquid/objects/app).

To learn more about conditional app blocks, refer to [Theme app extensions framework](https://shopify.dev/apps/online-store/theme-app-extensions/extensions-framework#conditional-app-blocks).
