Expand / Collapse is a simple helper function to allow you to more easily review your different levels of advertising activities. There are two icons on the main advertising activities screen, which when clicked apply to the currently select advertising activity.

The "Expand All" button is first. Simply select the activity for which you want to expand, then click the "Expand All" button to expand all the activity levels underneath.

Simirly, the "Collapse All" button works the same, but only in reverse. Again, simply select the activity for which you want to collapse, then click the "Collapse All" button to collapse the activity levels underneath.
