### Checkbox style

You can turn the radio buttons into a checkbox by adding a `"required": true` property. Additionally, you can set the default state by setting the `default` property.

### Nested parameters

By adding nested fields, you can add fields that will be shown to the user if this field’s value is `true`.

            "type": "text",
            "label": "Nested Field 2"
        }
    ]
  }
]
```

{% endtab %}
{% endtabs %}

### Editable (deprecated)

{% hint style="info" %}
Since **Apps platform version 2**, all Booleans have set `mappable`(editable) to `true` by default.
{% endhint %}

You can allow mapping to the field by setting `editable` to `true`.
