# Hide

Defines visibility for a report item for one output format.

### Description

The visibility rule says when a report item should be hidden. It can be hidden based on the output type, an expression, or both. For example, the browser control is normally hidden in all output formats except HTML. A past-due item might be hidden if the account is not past due.

An item can be completely hidden (hidden in all formats), or hidden only in selected formats. An item hidden in all formats is never actually created in the Factory. An item hidden in selected formats is created, but will be omitted when rendered to the format for which it is hidden.
