Spry effects are replaced with jQuery effects in Dreamweaver CC. While you can still modify existing spry effects on your page, you cannot add new spry effects.
Add jQuery effects
Specify the settings, such as, the target element to which the effect is to be applied, and the duration for the effect.
The target element can be the same as the element you selected initially or a different element on the page. For example, if you want users to click an element A to hide or show an element B, the target element is B.
Dreamweaver automatically inserts the relevant code into your document. For example, if you have selected the 'Fade' effect, the following code is inserted:
<li id="earthFrm" onclick="MM_DW_effectAppearFade($('#earthForms'),'show','fade',1000)"> Earth Forms</li>
Event-based jQuery effects
When you apply a jQuery effect, it is assigned to the onClick event by default. You can change the trigger event for the effect using the Behaviors panel.
