Answer 2

Answer:

The process in which by clicking the “plus sign” it changes to “minus sign” and “folder contents get displayed” is called “expanding of contents”. On clicking the “minus sign”, the contents will get hidden and this process is called “collapsing”. The “plus and minus controls” are known as the “progressive disclosure controls” as per the “Microsoft UX guide”. The purpose of these controls is to expand or collapse the content of the container.
