DefinitionA list box (リストボックス) is a GUI control that lines up prepared choices as a list inside a frame and has the user pick an item from them.
ExplanationThe choices stay visible on the screen, and any that do not fit in the frame are reached by scrolling. Because users pick from a fixed set, it prevents typing mistakes and inconsistent spellings that free text entry would allow. You can also preset the item that is already selected when the screen opens (the default value).
AnalogyIt is like looking at a list of school clubs pinned to a bulletin board and pointing at the one you want to join. Every option is visible from the start.
Memory hookSplit the name into list and box, and you picture a list sitting inside a box, always in view.
