/**
 * This hook provides support for suggestion creation in inputs which have choices.
 *
 * @param options The hook option
 * @param {ReactElement} options.create A react element which will be rendered when users choose to create a new choice. This component must call the `useCreateSuggestionContext` hook which provides `onCancel`, `onCreate` and `filter`. See the examples.
 * @param {String} options.createLabel Optional. The label for the choice item allowing users to create a new choice. Can be a translation key. Defaults to `ra.action.create`.
 * @param {String} options.createItemLabel Optional. The label for the choice item allowing users to create a new choice when they already entered a filter. Can be a translation key. The translation will receive an `item` parameter. Providing this option will turn the create label when there is no filter to be a hint (i.e. a disabled item).
 * @param {any} options.createValue Optional. The value for the choice item allowing users to create a new choice. Defaults to `@@ra-create`.
 * @param {any} options.createHintValue Optional. The value for the (disabled) item hinting users on how to create a new choice. Defaults to `@@ra-create-hint`.
 * @param {String} options.filter Optional. The filter users may have already entered. Useful for autocomplete inputs for example.
 * @param {OnCreateHandler} options.onCreate Optional. A function which will be called when users choose to create a new choice, if the `create` option wasn't provided.
 * @param {Function} options.handleChange A function to pass to the input. Receives the same parameter as the original event handler and an additional newItem parameter if a new item was create.
 *
 * @returns {UseSupportCreateValue} An object with the following properties:
 * - getCreateItem: a function which will return the label of the choice for create a new choice.
 * - handleChange: a function which should be called when the input value changes. It will call the `onCreate` function if the value is the createValue.
 * - createElement: a React element to render after the input. It will be rendered when users choose to create a new choice. It renders null otherwise.
 * - getOptionDisabled: a function which should be passed to the input to disable the create choice when the filter is empty (to make it a hint).
