/**
|
|
* The useList is a lower-level utility that is used to build list-like components.
|
|
* It's used to manage the state of the list and its items.
|
|
*
|
|
* Supports highlighting a single item and selecting an arbitrary number of items.
|
|
*
|
|
* The state of the list is managed by a controllable reducer - that is a reducer that can have its state
|
|
* controlled from outside.
|
|
*
|
|
* By default, the state consists of `selectedValues` and `highlightedValue` but can be extended by the caller of the hook.
|
|
* Also the actions that can be dispatched and the reducer function can be defined externally.
|
|
*
|
|
* @template ItemValue The type of the item values.
|
|
* @template State The type of the list state. This should be a subtype of `ListState<ItemValue>`.
|
|
* @template CustomAction The type of the actions that can be dispatched (besides the standard ListAction).
|
|
* @template CustomActionContext The shape of additional properties that will be added to actions when dispatched.
|
|
*
|
|
* @ignore - internal hook.
