Fieldnest – Custom Checkout Fields for WooCommerce

Fieldnest lets you add and manage custom fields on the new WooCommerce block-based checkout without writing code or reverting to the old [woocommerce_checkout] shortcode.

Many checkout field plugins were built for the classic (PHP) checkout and only partially support block checkout – so their custom fields silently fail to appear. Fieldnest is built block-first, on top of WooCommerce’s native Additional Checkout Fields API, so your fields actually show up, save to the order, and behave correctly.

Features

• Add custom text, dropdown (select) and checkbox fields to checkout
• Place fields in the Contact, Address, or Order sections
• Mark fields required or optional
• Reorder fields and remove them from a simple, no-code editor
• Fields save to the order and are available through the Store API
• No shortcode revert, no admin nag banners

Requires WooCommerce 8.9 or newer.
