A Pull-Down Menu is a secondary user interface element that appears beneath a primary menu item when selected. This feature provides additional navigation options and is commonly used in software applications and websites to enhance user experience and streamline access to various functions.
Features and Types of Pull-Down Menus
Common Features
- Hierarchical Structure: Pull-Down Menus often display a hierarchical arrangement of options, offering nested sub-menus.
- Clickable Options: Each item in the menu is typically clickable, leading the user to different actions or pages.

Types of Pull-Down Menus
Simple Pull-Down Menus
Simple Pull-Down Menus provide a straightforward list of options under a menu item. These are often used in basic navigation structures.
Nested Pull-Down Menus
Nested Pull-Down Menus contain multiple layers of options embedded within each other. These are used in more complex interfaces where categorization is necessary.
