Select State and Country in React JS | Dropdown List In React | Cascading Dropdown using ReactJS

This tutorial will show you how to create dependent or cascaded dynamic dropdowns using React JS. Sometimes you need to make such a cascaded dropdown where you need to select some value in the second dropdown based on the first dropdown value. For example, you may need to select the city dropdown value based on the country dropdown value and for this, you cannot pre-populate the city dropdown value unless you know the country value from the country dropdown.

I will explain here with an example using React. The example here contains two dropdowns – one dropdown will be displayed based on the selected parent dropdown value.
