Resetting a select to "Choose..." After Form Submission in React

When building forms in React, one common requirement is resetting the form elements after submission. A typical scenario involves ensuring that a dropdown menu (or select element) reverts to its default state—often displaying something like "Choose..." after a user submits the form. In this guide, we'll explore how to achieve this seamlessly in your React application.

The Challenge: Resetting the Dropdown

When the user submits a form with a select dropdown, there are times when we want to return it to its initial state (e.g., "Choose..."). By default, if we use the selected attribute in JSX, the dropdown will not reset unless explicitly managed.

The Right Approach

1. Managing State

To control the value displayed in the dropdown, we should use React's local state through the useState hook or class component state. This allows us to reset the dropdown value after the form is submitted.

2. Using Controlled Components

To create a controlled select element, we must set its value based on the component's state. This will allow us to update the dropdown dynamically.

Implementation: Step-by-Step Guide

Below, we will break down the steps on how to implement this using a class component example.

Step 1: Set Up State

Start by creating a new component and defining the initial state. We'll use a variable, selection, to keep track of the chosen value.

Step 2: Handling Changes

Next, manage the change in selection. When an option is selected, update the state accordingly:

Step 3: Form Submission Logic

Handle the form submission. In this handler, we'll also reset the state back to its initial value — this is how we make the dropdown go back to "Choose...".

Step 4: Rendering the Form

Finally, render the form with the select dropdown. Use the value prop to ensure the dropdown reflects the current state.

Resetting a select dropdown in React after a form submission can enhance user experience by making the form intuitive. By managing state effectively and implementing controlled components, developers can easily transition the dropdown back to its default option.
