TanStack Form Dynamic Fields and Reactivity

Use this skill when fields need to respond to changing form state or to other fields.

Scope

  • array fields and nested array paths
  • linked-field validation triggers
  • reactive reads through useStore and form.Subscribe
  • side effects through field and form listeners

Routing cues

  • mode="array", pushValue, removeValue, moveValue, swapValues, onChangeListenTo, onBlurListenTo, form.Subscribe, useStore, form.store, or debounced listeners -> this skill
  • validation timing, Standard Schema, custom errors, or disableErrorFlat -> tanstack-form-validation-and-errors
  • TanStack Query hydration, onSubmitMeta, or focus-first-error UX -> tanstack-form-data-loading-and-submission-ux
  • createFormHook and app-level wrappers -> tanstack-form-composition-and-ui-integration
