What is @react-stately/selection?

@react-stately/selection is a library that provides state management for selection in React applications. It is part of the React Spectrum collection of libraries and is designed to handle selection logic for lists, tables, and other components that require selection functionality.

What are @react-stately/selection's main functionalities?

Single Selection

This feature allows you to manage single selection state in a list. The code sample demonstrates how to use the `useSingleSelectListState` hook to manage the selection state of a list of items.

import { useSingleSelectListState } from '@react-stately/selection';

function SingleSelectList(props) {
  let state = useSingleSelectListState(props);

  return (
    <ul>
      {props.items.map((item) => (
        <li key={item.key} onClick={() => state.setSelectedKey(item.key)}>
          {item.name} {state.selectedKey === item.key && '(Selected)'}
        </li>
      ))}
    </ul>
  );
}

Multiple Selection

This feature allows you to manage multiple selection states in a list. The code sample demonstrates how to use the `useMultipleSelectionState` hook to manage the selection state of a list of items, allowing multiple items to be selected.

import { useMultipleSelectionState } from '@react-stately/selection';

function MultipleSelectList(props) {
  let state = useMultipleSelectionState(props);

  return (
    <ul>
      {props.items.map((item) => (
        <li key={item.key} onClick={() => state.toggleSelection(item.key)}>
          {item.name} {state.selectedKeys.has(item.key) && '(Selected)'}
        </li>
      ))}
    </ul>
  );
}

Selection Management

This feature provides a selection manager to handle complex selection logic. The code sample demonstrates how to use the `useSelectionManager` hook to manage selection actions like selecting all items, clearing selection, and toggling selection for individual items.

import { useSelectionManager } from '@react-stately/selection';

function SelectionManagerExample(props) {
  let manager = useSelectionManager(props.selectionState);

  return (
    <div>
      <button onClick={() => manager.selectAll()}>Select All</button>
      <button onClick={() => manager.clearSelection()}>Clear Selection</button>
      <ul>
        {props.items.map((item) => (
          <li key={item.key} onClick={() => manager.toggleSelection(item.key)}>
            {item.name} {manager.isSelected(item.key) && '(Selected)'}
          </li>
        ))}
      </ul>
    </div>
  );
}
