-You can customize the properties to use for the option name (instead of the default `name`) thanks to the `optionText` prop:
+By default, `<AutocompleteArrayInput>` uses the `name` property as the text content of each option.
 
 ```jsx
-const choices = [
-    { id: 'admin', label: 'Admin' },
-    { id: 'u001', label: 'Editor' },
-    { id: 'u002', label: 'Moderator' },

-`optionText` is especially useful when the choices are records coming from a `<ReferenceArrayInput>` or a `<ReferenceManyToManyInput>`. By default, react-admin uses the [`recordRepresentation`](./Resource.md#recordrepresentation) function to display the record label. But if you set the `optionText` prop, react-admin will use it instead.
+If your `choices` don't have a `name` property, or if you want to use another property, you can use the `optionText` prop to specify which property to use:
 
 ```jsx
-<ReferenceArrayInput source="tag_ids" reference="tags">
-    <AutocompleteArrayInput optionText="tag" />
-</ReferenceArrayInput>
+<AutocompleteArrayInput
+    source="categories"
