# Tabs.State

The visible panel selection, focused tab identity, and activation policy.
Manual activation allows `activeId` to differ from `selectedId` until the user commits.

## Signatures

```ts
export interface State extends Omit<Composite.State, "orientation"> {
    readonly orientation: Orientation;
    readonly selectedId: string;
    readonly activeId: string;
    readonly activationMode: ActivationMode;
}
```
