# FormResetOptions

# Interface: FormResetOptions

Defined in: [FormApi/FormApi.public.ts:526](https://github.com/TanStack/form/blob/main/packages/form-core/src/FormApi/FormApi.public.ts#L526)

Options controlling whether `reset(values)` replaces the default-value
baseline.

## Example

```ts
formApi.reset(savedValues, { updateDefaultValues: false })
```

## Properties

### updateDefaultValues?

```ts
optional updateDefaultValues?: boolean;
```

Defined in: [FormApi/FormApi.public.ts:556](https://github.com/TanStack/form/blob/main/packages/form-core/src/FormApi/FormApi.public.ts#L556)

Whether `reset(values)` should also update the form's `defaultValues`
baseline.

By default, passing values to `reset` treats those values as the new reset
baseline. Future `reset()` calls will return to those values, and
`state.isDefaultValue` will compare against them.

Set this to `false` when you want reset semantics for form state
(clearing touched, dirty, validation, submission state, and mounted fields)
but want to keep comparing against the previous `defaultValues`.

With `updateDefaultValues: false`, `state.isDirty` is reset to `false`,
but `state.isDefaultValue` may be `false` if the provided reset values do
not deeply equal the preserved defaults.

This option is ignored when no reset values are provided.

#### Example

```ts
const originalDefaults = formApi.defaultValues

formApi.reset(savedDraft, { updateDefaultValues: false })
// `savedDraft` is current, but `originalDefaults` remains the baseline.

formApi.reset()
// Restores `originalDefaults`, not `savedDraft`.
```
