# Field primitive (/docs/components/primitives/field)
Use field primitives when you are building a composed field component that needs Luke UI label,
description, and error styling.
```tsx
import { Field, FieldLabel, FieldDescription, FieldError } from '@luke-ui/react/field/primitive';
```
## Anatomy [#anatomy]
`Field` composes the common field structure: label, control slot, description, and validation
message.
Use `FieldLabel`, `FieldDescription`, and `FieldError` directly when a composed component needs a
custom layout.
```tsx
```
## Necessity indicators [#necessity-indicators]
`FieldLabel` accepts `necessityIndicator`. Use it to choose how required fields are shown.
```tsx
```
## Props [#props]
### Field [#field]
### FieldLabel [#fieldlabel]
### FieldDescription [#fielddescription]
### FieldError [#fielderror]
