The Code Field saves a string in the database, but provides the [Admin Panel](../admin/overview) with a code editor styled interface.
To add a Code Field, set the `type` to `code` in your [Field Config](./overview):
```ts
import type { Field } from 'payload'
export const MyBlocksField: Field = {
// ...
type: 'code', // highlight-line
}
```
## Config Options
| Option | Description |
| ---------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **`name`** \* | To be used as the property name when stored and retrieved from the database. [More](/docs/fields/overview#field-names) |
| **`label`** | Text used as a field label in the Admin Panel or an object with keys for each language. |
| **`unique`** | Enforce that each entry in the Collection has a unique value for this field. |
| **`index`** | Build an [index](/docs/database/overview) for this field to produce faster queries. Set this field to `true` if your users will perform queries on this field's data often. |
| **`minLength`** | Used by the default validation function to ensure values are of a minimum character length. |
| **`maxLength`** | Used by the default validation function to ensure values are of a maximum character length. |
| **`validate`** | Provide a custom validation function that will be executed on both the Admin Panel and the backend. [More](/docs/fields/overview#validation) |
| **`saveToJWT`** | If this field is top-level and nested in a config supporting [Authentication](/docs/authentication/overview), include its data in the user JWT. |
| **`hooks`** | Provide Field Hooks to control logic for this field. [More details](../hooks/fields). |
| **`access`** | Provide Field Access Control to denote what users can see and do with this field's data. [More details](../access-control/fields). |
| **`hidden`** | Restrict this field's visibility from all APIs entirely. Will still be saved to the database, but will not appear in any API or the Admin Panel. |
| **`defaultValue`** | Provide data to be used for this field's default value. [More](/docs/fields/overview#default-values) |
| **`localized`** | Enable localization for this field. Requires [localization to be enabled](/docs/configuration/localization) in the Base config. |
| **`required`** | Require this field to have a value. |
| **`admin`** | Admin-specific configuration. See below for [more detail](#admin-options). |
| **`custom`** | Extension point for adding custom data (e.g. for plugins) |
| **`typescriptSchema`** | Override field type generation with providing a JSON schema |
| **`virtual`** | Provide `true` to disable field in the database, or provide a string path to [link the field with a relationship](/docs/fields/relationship#linking-virtual-fields-with-relationships). See [Virtual Fields](https://payloadcms.com/blog/learn-how-virtual-fields-can-help-solve-common-cms-challenges) |
_\* An asterisk denotes that a property is required._
## Admin Options
To customize the appearance and behavior of the Code Field in the [Admin Panel](../admin/overview), you can use the `admin` option:
```ts
import type { Field } from 'payload'
export const MyCodeField: Field = {
// ...
admin: {
// highlight-line
// ...
},
}
```
The Code Field inherits all of the default admin options from the base [Field Admin Config](./overview#admin-options), plus the following additional options:
| Option | Description |
| ------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **`language`** | This property can be set to any language listed [here](https://github.com/microsoft/monaco-editor/tree/main/src/basic-languages). |
| **`editorOptions`** | Options that can be passed to the monaco editor, [view the full list](https://microsoft.github.io/monaco-editor/typedoc/interfaces/editor.IDiffEditorConstructionOptions.html). |
## Example

type: 'code', // required
required: true,
admin: {
language: 'javascript',
},
},
],
}
