How to Show Form Input Fields Based on Select Value in React?
In ReactJS, you can show or hide input fields based on the selected value of a dropdown (select) element by using conditional rendering. Listen for the onChange event of the select element, and, based on the selected value, conditionally render the relevant input fields using ternary operators or if statements. Create state variables to manage the visibility of input fields. When the select value changes, update the state accordingly to show or hide the input fields. This allows for a dynamic user interface where certain input fields are displayed or hidden based on the user's selection.
