How can I change the color of a dropdown option in ReactJS when it is selected?
This code snippet is a React.js component that renders a dropdown select element with various options. It uses the useState hook to manage the selected option's value.
The handleOptionChange function is called when the selected option changes, updating the selectedValue state.
Each option element has a className attribute that is conditionally set based on whether its value matches the selectedValue. This allows you to change the color of the selected option using CSS styles.
