This piece explains when a form can stay a simple UI and when it turns into a rules-heavy system, with practical guidance for choosing the right React and Next.js approach.

Good read on when dynamic forms in React and Next.js are just UI and when they start acting like rule engines.

The useful split is whether your branching is just conditional UI or whether you’re really managing a rules system with state, validation, and change history. Once visibility, defaults, and validation all depend on prior answers, I’d stop thinking “form component” and start thinking “workflow model.”

```tsx
const showBusinessFields = values.accountType === "business";
const taxIdRequired = showBusinessFields && values.country === "US";

return (
  <>
    {showBusinessFields && <BusinessFields />}
    <Input name="taxId" required={taxIdRequired} />
  </>
);

```

I agree with the split, though I’d add that many teams jump to a workflow engine too early when a small derived-state layer is enough.

```tsx
const ctx = { business: values.accountType === "business" };
const rules = {
  showBusinessFields: ctx.business,
  taxIdRequired: ctx.business && values.country === "US",
};

```
