A tree menu is a hierarchical menu that can be expanded or collapsed. It is useful for organizing information and presenting it in an organized way. It can be used on websites and in file systems, and different programming languages can be used to create it.
A tree menu is a menu that displays a hierarchy of items that can be expanded or collapsed at the viewer’s convenience. Many of the browsers used to manage file systems on a hard drive are in the form of tree menus, which allow people to click buttons to expand various folders within the file system to see what’s inside, and a cascading effect can be created with numerous menu branches nested inside each other. This type of menu can also be used on a website that wants to present information in an organized way.
Tree menus are useful for several reasons. Because they can be collapsed and expanded, they can be used to display a lot of information without overwhelming the viewer. For example, a travel site might have a tree menu with the top-level titles “Asia”, “Africa” and “South America”, and when someone clicked the button to expand “Africa”, a list of subtitles such as “South Africa”, “Equatorial Africa” and “North Africa” might appear, with each subtitle containing subtitles for various nations that could be expanded into regions, cities, and so on. The alternative would be to display a huge menu that would be daunting to navigate and show unnecessary information; someone who wants information about the Great Wall of China, for example, doesn’t need to see information about Egypt.
People can also use a tree menu to explore the relationship between items in a list. People with highly organized file schemas like tree menus because the menu allows them to create a more precise set of categories for their information, from a broad topic like “pictures” to a more specific one like “Hawaii Trip.” Tree menus also make navigation easier for people who are not familiar with the information, as the presentation is clear and easy to understand.
On websites, different programming languages can be used to create tree menus. Flash and a number of scripts can be used to create more eye-catching tree menus, and tools such as PHP and HTML can also be used, depending on the desired look of the menu and the skill level of the programmer. Several companies sell dynamic tree menu code that people can simply push into place, and free versions are also available.
Many software programs that organize bulletin boards, files on an FTP site, and so on use tree menu schemes to present information. Users can be presented with different options including a “tree view” and can select the view version they feel most comfortable with.
