# `sortRequiredPropsFirst`

By default, fields are rendered in the order they appear in the API description.

The `sortRequiredPropsFirst` option changes the order to display required fields first in each schema section.

## Options

| Option | Type | Description |
|  --- | --- | --- |
| sortRequiredPropsFirst | boolean | Sort the required schema properties before the optional ones. Default value is `false`. |


## Examples

The following example configures Redoc to show required properties first:


```yaml redocly.yaml
openapi:
  sortRequiredPropsFirst: true
```
