​[UForm] Feature Request: Make deferInputValidation Configurable in useFormField​​

[brin000]

Description

🔧 Current Behavior

The deferInputValidation parameter in useFormField is currently hardcoded in the Input component:

const { emitFormBlur, emitFormInput, /* ... */ } = useFormField<InputProps>(props, { 
  deferInputValidation: false // Hardcoded
})

This limits flexibility, as consumers of the Input component cannot control validation timing behavior (e.g., validate on blur vs. validate on input).

✅ Proposed Solution

Make deferInputValidation configurable via a component prop:

1. Pass dynamic value to useFormField:

useFormField<InputProps>(props, {
  deferInputValidation: props.deferInputValidation
})

2. Update the component props interface:

deferInputValidation?: boolean

💡 Use Cases

• Delayed validation for complex, interdependent form fields
• Immediate validation for sensitive or critical fields
• Flexibility for UX patterns like "validate-on-blur" or "validate-as-you-type"

---

🔁 Alternatives Considered

• Wrapper Component: Adds unnecessary complexity
• Global Form-Level Config: Less flexible than per-field control

---

🧪 Testing Impact

• Covered by existing validation tests with both true and false cases

---

📚 Documentation

Requires updates to:

• Component prop API
• Form validation best practices

---

⚙️ Why This Matters

This change supports Inversion of Control — empowering component consumers to control validation timing based on specific UX needs.
