What are collapsed and expanded views?
While viewing forums in a collapsed view, only the details of the first post in a thread will be displayed. The expanded view displays the details of all posts within a thread. Collapsed/expanded views can be toggled with the "Collapsed View/Expand All Threads" button at the top of the list of threads. Individual threads can be expanded and collapsed using the buttons to the left of each thread's title. See the Legend at the bottom of the thread list for details about these buttons. You can set your default preference in your Display Profile.
