TypeError: p.easing[this.easing] is not a function

You need to include jQueryUI for the extended easing options.

I think there may be an option to only include the easing in the download, or at least just the base library plus easing.

For those who have a custom jQuery UI build (bower for ex.), add the effects core located in ..\jquery-ui\ui\effect.js.

Including this worked for me.

Please include the line mentioned below in the section.

<script src='http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.5/jquery-ui.min.js'>
