The below combobox that enables users to choose a term from a hypothetical list of previously searched terms demonstrates the
ARIA design pattern for combobox.
The design pattern describes four types of autocomplete behavior.

.
The terms that appear in the listbox popup are not related to the string that is present in the textbox.
In this implementation, The listbox popup is not automatically triggered; it is displayed only when the user opens it.
