Using external state in React Storybook involves passing data and state from a parent component to its child components via props.

Here are some steps to properly use external state in React Storybook:

1. Define the external state in the parent component: First, define the data and state in the parent component that you want to pass down to its child components.
2. Pass the external state as props to child components: Use the props to pass the external state down to the child components. Make sure to update the state in the parent component and pass the updated state as props whenever it changes.
3. Create stories in Storybook for the parent and child components: In Storybook, create stories for both the parent and child components. Make sure to pass the external state as props to the child components in the stories.
4. Update the stories to display the external state: In the stories, update the child components to display the external state that is passed down as props. This will allow you to see how the external state affects the child components in Storybook.
5. Test and verify the external state: Finally, test and verify that the external state is properly passed down to the child components and that the components render correctly in Storybook.

By following these steps, you can effectively use external state in React Storybook and see how it affects the rendering of your components.
