 Property | Type | Description
 :---|:---|:---
+`children` | function | Child function responsible for creating the inner Select component. This component can be used to compose HOCs (eg Creatable and Async). Expected signature: `(props: Object): PropTypes.element` |
 `isOptionUnique` | function | Searches for any matching option within the set of options. This function prevents duplicate options from being created. By default this is a basic, case-sensitive comparison of label and value. Expected signature: `({ option: Object, options: Array, labelKey: string, valueKey: string }): boolean` |
 `isValidNewOption` | function | Determines if the current input text represents a valid option. By default any non-empty string will be considered valid. Expected signature: `({ label: string }): boolean` |
 `newOptionCreator` | function | Factory to create new option. Expected signature: `({ label: string, labelKey: string, valueKey: string }): Object` |
+`promptTextCreator` | function | Creates prompt/placeholder option text. Expected signature: `(filterText: string): string`
 `shouldKeyDownEventCreateNewOption` | function | Decides if a keyDown event (eg its `keyCode`) should result in the creation of a new option. ENTER, TAB and comma keys create new options by dfeault. Expected signature: `({ keyCode: number }): boolean` |
+`promptTextCreator` | function | Factory for overriding default option creator prompt label. By default it will read 'Create option "{label}"'. Expected signature: `(label: String): String` |

+### Combining Async and Creatable
+
+Use the `AsyncCreatable` HOC if you want both _async_ and _creatable_ functionality.
+It ties `Async` and `Creatable` components together and supports a union of their properties (listed above).
+Use it as follows:
+
+```jsx
+import React from 'react';
+import { AsyncCreatable } from 'react-select-plus';
+
+function render (props) {
+  // props can be a mix of Async, Creatable, and Select properties
+  return (
+    <AsyncCreatable {...props} />
+  );
+}
+```
