Form Components Skill

Core Rule

ALWAYS use form components from @/components/ui/form-fields.

These components:

• Auto-generate id/name attributes
• Include accessibility features (aria-describedby, aria-invalid)
• Consistent styling across the app
• Proper label association

Accessibility Features

The form components automatically provide:

1. Label Association

Copy<!-- Generated HTML -->
<label for="user-email">Email Address</label>
<input id="user-email" name="user-email" />

2. Error Announcements

Copy<!-- When error prop is provided -->
<input
  id="user-email"
  aria-invalid="true"
  aria-describedby="user-email-error"
/>
<p id="user-email-error" role="alert">Invalid email address</p>

3. Description Association

Copy<input aria-describedby="user-email-description" />
<p id="user-email-description">We'll never share your email</p>

Form Patterns

Basic Form

Copyimport { FormInput, FormSelect, FormCheckbox } from "@/components/ui/form-fields";

function MyForm() {
  const [formData, setFormData] = useState({
    email: '',
    role: '',
    newsletter: false,
  });
  const [errors, setErrors] = useState({});

  return (
    <form onSubmit={handleSubmit}>
      <FormInput
        fieldName="email"
        label="Email"
        type="email"
        value={formData.email}
        onChange={(e) => setFormData(prev => ({ ...prev, email: e.target.value }))}
        error={errors.email}
        required
      />
      
      <FormSelect
        fieldName="role"
        label="Role"
        value={formData.role}
        onChange={(e) => setFormData(prev => ({ ...prev, role: e.target.value }))}
        required
      >
        <option value="">Select role...</option>
        <option value="member">Member</option>
        <option value="admin">Admin</option>
      </FormSelect>
      
      <FormCheckbox
        fieldName="newsletter"
        label="Subscribe to newsletter"
        checked={formData.newsletter}
        onChange={(e) => setFormData(prev => ({ ...prev, newsletter: e.target.checked }))}
      />
      
      <button type="submit">Submit</button>
    </form>
  );
}

With Loading State

Copy<FormInput
  fieldName="email"
  label="Email"
  disabled={isSubmitting}
/>

<button type="submit" disabled={isSubmitting}>
  {isSubmitting ? "Saving..." : "Save"}
</button>

Anti-Patterns

❌ Don't Use Raw HTML Elements

Copy// ❌ WRONG
<label>Email</label>
<input type="email" name="email" />

// ✅ CORRECT
<FormInput fieldName="email" label="Email" type="email" />

❌ Don't Forget fieldName

Copy// ❌ WRONG - no fieldName
<FormInput label="Email" type="email" />

// ✅ CORRECT
<FormInput fieldName="email" label="Email" type="email" />

❌ Don't Duplicate IDs

Copy// ❌ WRONG - duplicate fieldNames
<FormInput fieldName="email" label="Email" />
<FormInput fieldName="email" label="Confirm Email" />

// ✅ CORRECT - unique fieldNames
<FormInput fieldName="email" label="Email" />
<FormInput fieldName="confirm-email" label="Confirm Email" />
