# @fayegram-ai/faye-ui/motion/transition-group

Public exports and dependency-resolved component properties, with usage and rendering guidance.

## Import

```tsx
import { TransitionGroup } from '@fayegram-ai/faye-ui/motion/transition-group';
```

[Usage and behavior guide](/docs/motion/) · [API JSON](/api/packages/motion/transition-group.json)

This entry declares a client boundary. Follow the rendering guide for framework integration.

## Public exports

| Name | Kind | Resolved declaration type |
|---|---|---|
| `TransitionGroup` | value | `({ children, mode, effect, appear, direction, enterDuration, exitDuration, onExitComplete, layout, className, ...props }: TransitionGroupProps) => import("react").JSX.Element` |
| `TransitionGroupProps` | type | `TransitionGroupProps` |

## TransitionGroup

Retains removed keys for their exit; re-entry cancels removal and preserves child state.

Dependency-resolved declaration properties. Common React/native HTML attributes are omitted from the table; use the full declaration and React/native references. Generic and union restrictions remain authoritative in TypeScript.

### Properties

| Property | Required | Type | Meaning |
|---|---|---|---|
| `appear` | No | `boolean \| undefined` | See the usage contract and declaration. |
| `children` | Yes | `ReactElement<unknown, string \| JSXElementConstructor<any>> \| readonly ReactElement<unknown, string \| JSXElementConstructor<any>>[]` | See the usage contract and declaration. |
| `direction` | No | `"start" \| "end" \| "left" \| "right" \| "up" \| "down" \| undefined` | See the usage contract and declaration. |
| `effect` | No | `"scale" \| "fade" \| "slide" \| "collapse" \| undefined` | See the usage contract and declaration. |
| `enterDuration` | No | `number \| undefined` | See the usage contract and declaration. |
| `exitDuration` | No | `number \| undefined` | See the usage contract and declaration. |
| `layout` | No | `boolean \| undefined` | Animate keyed position changes in stack mode, preserving child state and focus. |
| `mode` | No | `"overlap" \| "stack" \| undefined` | See the usage contract and declaration. |
| `onExitComplete` | No | `((key: string) => void) \| undefined` | See the usage contract and declaration. |



## Defaults and customization

Defaults and native behavior are documented in the linked family guide. This reference does not infer a default from an optional property.

Use semantic tokens, public part hooks and customization sheets. Keep visual configuration separate from application state.

## State, events and accessibility

For interactive controls, pair a controlled value/open prop with its corresponding change callback; default props initialize uncontrolled state. Keep application validation and submission policy explicit. Name controls with visible labels, name icon-only actions on the button, and preserve focus and dismissal behavior when replacing parts. Use native form names and submit/reset types where supported. See the usage guide for component-specific behavior and live examples.

## Declaration authority

Generated from `packages/faye-ui/dist/motion/transition-group.d.ts` after the semantic package build. Common native/React attributes are intentionally omitted from property tables. Generic overloads, discriminated unions and complete inherited attributes remain authoritative in installed TypeScript declarations. [React DOM attributes](https://react.dev/reference/react-dom/components/common) and [Base UI component contracts](https://base-ui.com/react/overview/quick-start) describe the inherited foundations.
