Scriptaculous Helpers
Provides a set of helpers for calling Scriptaculous JavaScript
functions, including those which create AJAX controls and visual effects.
To be able to use these helpers, you must include the Prototype
JavaScript framework and the Scriptaculous JavaScript library in your
pages.
The Scriptaculous helpers' behavior can be tweaked with various options.
See the documentation at http://script.aculo.us for more information on
using these helpers in your application.

If no element_id is given, it assumes "element" which should be a local
variable in the generated JavaScript execution context. This can be
used for example with drop_receiving_element::
<% drop_receving_element('some_element', loading=visual_effect('fade')) %>
This would fade the element that was dropped on the drop receiving
element.
For toggling visual effects, you can use ``toggle_appear``,
``toggle_slide``, and ``toggle_blind`` which will alternate between
appear/fade, slidedown/slideup, and blinddown/blindup respectively.
You can change the behaviour with various options, see
http://script.aculo.us for more documentation.

Wrap visual effects so they occur in parallel.
Example::
parallel_effects(
visual_effect('highlight, 'dom_id'),
visual_effect('fade', 'dom_id'),
)

Make the element with the DOM ID specified by ``element_id`` sortable.
Uses drag-and-drop and makes an Ajax call whenever the sort order has
changed. By default, the action called gets the serialized sortable
element as parameters.
Example::
<% sortable_element("my_list", url=url(action="order")) %>
In the example, the server-side action gets a "my_list" array
parameter containing the values of the ids of elements the
sortable consists of, in the current order (like
``mylist=item1&mylist=item2``, where ``item1`` and ``item2`` are
the ids of the ```` elements).
Note: For this to work, the sortable elements must have id
attributes in the form ``string_identifier``. For example,
``item_1``. Only the identifier part of the id attribute will be
serialized.
You can change the behaviour with various options, see
http://script.aculo.us for more documentation.
