React Js Dynamic Select Option using Fetch Api:To create a dynamic select option in ReactJS using the Fetch API, you can follow these steps. First, define a state variable to hold the options data. Then, use the useEffect hook to make a fetch request to the server using the Fetch API and update the state with the received data.
Next, render a select element and map over the options data to generate the option elements dynamically. Finally, set an onChange event handler to update the selected value in the state. This way, whenever the options data changes, the select options will be updated dynamically, providing a seamless user experience.
