The Array field type is used when you need to have a set of "repeating" fields. It stores an array of objects containing the fields that you define. Its uses can be simple or highly complex.
|
|

|
|
|
|
**Example uses:**
|
|
|
|
- A "slider" with an image ([upload field](/docs/fields/upload)) and a caption ([text field](/docs/fields/text))
|
|
- Navigational structures where editors can specify nav items containing pages ([relationship field](/docs/fields/relationship)), an "open in new tab" [checkbox field](/docs/fields/checkbox)
|
|
- Event agenda "timeslots" where you need to specify start & end time ([date field](/docs/fields/date)), label ([text field](/docs/fields/text)), and Learn More page [relationship](/docs/fields/relationship)

### Config
|
|
|
|
| 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 the heading in the Admin panel or an object with keys for each language. Auto-generated from name if not defined. |
|
|
| **`fields`** * | Array of field types to correspond to each row of the Array. |
|
|
| **`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/config), include its data in the user JWT. |
|
|
| **`hooks`** | Provide field-based hooks to control logic for this field. [More](/docs/fields/overview#field-level-hooks) |
|
|
| **`access`** | Provide field-based access control to denote what users can see and do with this field's data. [More](/docs/fields/overview#field-level-access-control) |
|
|
| **`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 an array of row 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. If enabled, a separate, localized set of all data within this Array will be kept, so there is no need to specify each nested field as `localized`. |
|
|
| **`required`** | Require this field to have a value. |
|
|
| **`labels`** | Customize the row labels appearing in the Admin dashboard. |
|
|
| **`admin`** | Admin-specific configuration. See below for [more detail](#admin-config). |
|
|
| **`custom`** | Extension point for adding custom data (e.g. for plugins) |
|
|
|
|
*\* An asterisk denotes that a property is required.*
|
|
|
|

|
|
|
| Option | Description |
|
|
| ---------------------- | ------------------------------- |
|
|
| **`initCollapsed`** | Set the initial collapsed state |
|
|
| **`components.RowLabel`** | Function or React component to be rendered as the label on the array row. Receives `({ data, index, path })` as args |
