The useSelect hook enables blocks to access WordPress store data by providing a callback function that receives the select function. This connects React components to the Redux store seamlessly.
Data must be retrieved before the return statement and stored in variables for use in the component’s JSX. Use conditional rendering to display different content based on store data, like sidebar open/closed states.
The useSelect hook automatically re-renders components when subscribed store data changes, creating reactive interfaces that respond to editor state changes without additional event handling.
