		<desc>If the value is an object, then <code>effect</code>, <code>delay</code>, <code>duration</code>, and <code>easing</code> properties may be provided. If the <code>effect</code> property contains the name of a jQuery method, then that method will be used; otherwise it is assumed to be the name of a jQuery UI effect. When using a jQuery UI effect that supports additional settings, you may include those settings in the object and they will be passed to the effect. If <code>duration</code> or <code>easing</code> is omitted, then the default values will be used. If <code>effect</code> is omitted, then <code>"fadeIn"</code> will be used.  If <code>delay</code> is omitted, then no delay is used.</desc>
