While designing a report, you may find it helpful to Suppress (hide) sections, easily Revealing them later.
Within Crystal, right-click on the Section name on the left hand section of the designer.
Then select Hide or Suppress, depending on your need.
Hide will still allow you to "Drill Down" and see the section in question.
Suppress will not allow you to reveal the section at all until you right-click on it and select Show.
