Definition
A drop-down menu is a graphical control element, typically found in graphical user interfaces (GUIs) of computer applications, that allows a user to choose one value from a list. When the menu title or menu item is selected, the list of options “drops down” beneath it as the user activates it, presenting all available choices.
Examples
- Web Forms: In online forms, drop-down menus allow users to select their country, state, age group, etc.
- Software Applications: Common in computer applications such as Microsoft Office, where drop-down menus offer options for formatting, editing, and other functionalities.
- Navigation Menus: On websites, drop-down menus are frequently used in navigation bars to categorize and present links in an organized manner.
Frequently Asked Questions (FAQs)
What is the difference between a drop-down menu and a pop-up menu?
A drop-down menu is attached to a menu item and “drops down” to reveal options, while a pop-up menu typically appears anywhere within the application’s window as a context menu, usually on right-click.
When designed properly following web accessibility guidelines (like the WCAG), drop-down menus can be accessible. This involves ensuring they are operable via keyboard and are recognized by screen readers.
Drop-down menus can be created using HTML, CSS, and JavaScript. HTML for the structure, CSS for styling, and JavaScript for handling user interactions.
A nested drop-down menu contains submenus, where hovering over or clicking a menu item in the parent drop-down reveals another drop-down list.
Can drop-down menus handle multi-select?
Typically, a standard drop-down menu handles single selection. For multi-select functionality, developers often use checkboxes within the drop-down.
- Fly-Out Menu: A sub-menu that appears adjacent to the main menu rather than below it.
- Popup Menu: A menu that appears upon a user action like a right-click anywhere in the application window.
- Pull-Down Menu: Another term for drop-down menu, often used when the action involves pulling down the options directly below the menu title.
