-The Create Content Model plugin builds upon our custom post types project at the [CloudFest Hackathon in 2024](https://wordpress.com/blog/2024/04/15/custom-post-types-wordpress-admin/). We’ve leveraged core functionality, like [block bindings](https://make.wordpress.org/core/2024/03/06/new-feature-the-block-bindings-api/) and [block variations](https://developer.wordpress.org/block-editor/reference-guides/block-api/block-variations/), to create a new paradigm for creating and managing custom post types and custom fields in WordPress.

 Unlike existing custom post type and custom field plugins, our plugin takes a native approach by putting the creation and management of these elements directly in the WordPress Block Editor. Using the Block Bindings API, `post_meta` fields are bound to block attributes. Block variations are created from each bound block for use in front-end template layouts. The result is an extremely intuitive workflow for both the setup of custom post types and fields and their usage in front-end templating.
