Form inputs are elements in a web form that allow users to enter data. Common types of form inputs include text fields, checkboxes, radio buttons, and dropdown menus. These inputs help collect information such as names, email addresses, and preferences from users, making it easier for websites to process requests or feedback. When users fill out a form, they interact with these inputs to provide the necessary information. For example, a registration form may include a text field for a username and a checkbox for agreeing to terms and conditions. Properly designed form inputs enhance user experience and data accuracy.
