# ErrorSummary

A linked validation summary that focuses host-owned invalid fields.

Connect Flood once using [the installation guide](https://flood.md/docs/installation). Then import the components you use; no per-component add command is needed.

## Example

```tsx
"use client";

import { FloodRoot, ErrorSummary } from "@flood-md/react";
import "@flood-md/react/styles.css";

export function Example() {
  return (
    <FloodRoot>
      <ErrorSummary title="Review the form" errors={[{id:"project",fieldId:"project",message:"Enter a project name."}]} />
    </FloodRoot>
  );
}
```

## Design notes

- The host supplies errors; ErrorSummary does not infer validation or submit a form. Each entry links to an exact field ID.
- Normal activation focuses the target while modifier navigation remains native. onSelect can cancel the action before focus moves.
- announcement defaults to off. autoFocus opts into focus on appearance, not on every error update, and suppresses duplicate live announcements. Empty errors render nothing. Introduced in 0.2.7.
