.show( effect [, options ] [, duration ] [, complete ] )Returns: jQuery

Description: Display the matched elements, using custom effects.

This plugin extends jQuery's built-in .show() method. If jQuery UI is not loaded, calling the .show() method may not fail directly, as the method still exists. However, the expected behavior will not occur.

Example:

Show a div using the fold effect.
