+# `<TextArrayField>`
+
+`<TextArrayField>` renders an array of scalar values using Material-UI's Stack and Chips.
+
+![TextArrayField](./img/text-array-field.png)
+
+`<TextArrayField>` is ideal for displaying lists of simple text values, such as genres or tags, in a visually appealing way.
+
+## Usage
+
+`<TextArrayField>` can be used in a Show view to display an array of values from a record. For example:
+
+```js
+const book = {
+    id: 1,
+    title: 'War and Peace',
+    genres: [
+        'Fiction',
+        'Historical Fiction',
+        'Classic Literature',
+        'Russian Literature',
+    ],
+};
+```
+
+You can render the `TextArrayField` like this:
+
+```jsx
+import { Show, SimpleShowLayout, TextArrayField } from 'react-admin';
+
+const BookShow = () => (
+    <Show>
+        <SimpleShowLayout>
+            <TextField source="title" />
+            <TextArrayField source="genres" />
+        </SimpleShowLayout>
+    </Show>
+);
+```
+
+## Props
+
+The following props are available for `<TextArrayField>`:
+
+| Prop        | Type         | Required | Description                                                   |
+| ----------- | ------------ | -------- | ------------------------------------------------------------- |
+| `source`    | `string`     | Yes      | The name of the record field containing the array to display. |
+| `color`     | `string`     | -        | The color of the Chip components.                             |
+| `emptyText` | `ReactNode`  | -        | Text to display when the array is empty.                      |
+| `record`    | `RecordType` | -        | The record containing the data to display.                    |
+| `size`      | `string`     | -        | The size of the Chip components.                              |
+| `variant`   | `string`     | -        | The variant of the Chip components.                           |

+
+## `direction`
