# Optional features

Metafield and metaobject definitions each come with a series of optional features you can opt into called `capabilities`.

This lets you mix in behaviors and logic with your metafields and metaobjects, to unlock the right functionality for your use case. Capabilities are diverse, from adding [theme templates to a metaobject](https://shopify.dev/docs/apps/build/custom-data/metaobjects/use-metaobject-capabilities#make-your-metaobjects-render-web-pages-in-the-online-store), to enabling a metafield to [drive filters](https://shopify.dev/docs/apps/build/custom-data/metafields/use-metafield-capabilities#admin-filterable) in the Shopify admin and GraphQL Admin API.

Metafield definitions come with the following [capabilities](https://shopify.dev/docs/apps/build/custom-data/metafields/use-metafield-capabilities):
