How to Implement a Nested Autocomplete in Material-UI?

Implementing an autocomplete feature in your Material-UI-based application enhances user experience by offering dynamic suggestions as users type. But if you have a more complex dataset, you might need to implement a nested autocomplete to handle layers of suggestions efficiently. Let's go through a comprehensive guide on how to achieve this with Material-UI.

Why Nested Autocomplete?

Nested autocomplete is particularly useful when you want to categorize suggestions or provide hierarchical data, like city names within countries or subcategories within categories. It makes navigation and selection more intuitive for the users.

Prerequisites

Ensure you have the following installed in your project:

Material-UI: The core and lab packages.

React: Since this guide assumes a React project setup.
