Auto-complete functionality in a search bar utilizes algorithms that analyze previous searches, popular trends, and user behavior to generate a list of suggested search queries. As you type, the search bar displays the most relevant suggestions based on what you've entered so far.

Creating a Basic Search Bar - <input type="text"> creates a text field for user input. The type="text" attribute specifies that the input should be a text field. - placeholder="Search..." is an attribute of the <input> tag that provides a hint to the user about what they should type in the text field.

Example Explained Use any element to open the dropdown menu, e.g. a <button>, <a> or <p> element. Use a container element (like <div>) to create the dropdown menu and add the dropdown links inside it. Wrap a <div> element around the button and the <div> to position the dropdown menu correctly with CSS.
