Hi Jerry,
You can still use a WOConditional to make the content visible and
invisible. Just wrap the conditional with an AjaxUpdateContainer and
change your WOHyperlink to an AjaxUpdateLink (with an action method
that changes the WOConditional's boolean). I'd make it work without
ajax first, and then add the ajax parts.

As John said... Or, if you want to load the content when the main
page loads, you could use a tiny bit of JavaScript. Suppose you put
the area to be shown (and hidden?) in a
<div id="showAndHideThis" style="display: none;">Your content here.<div>
Then you can use something like
<a href="#showAndHideThis" onClick="Element.toggle
('showAndHideThis');">Click to show the hidden content</a>
The Element.toggle function is part of prototype, which will already
be included if you use an AjaxUpdateContainer on the page. You can of
course still use an update container within the div.
cheers

I'm trying to use Ajax to make an updatable area of the page appear
and disappear (similar to content in a WOConditional, but without
page refresh).
I've checked out the Project Wonder libraries and have installed the
Ajax and the ERExtensions Frameworks to satisfy a client's request
for Ajax interaction with his web site.
The components are very well integrated, thanks Project Wonder guys!
However, in the short time I've been experimenting with them, I'm
unable to see how to use them to satisfy this specific request from
my client.
On the GoogleMail page ( http://mail.google.com/mail/ ), for those
who use GoogleMail, a user can click on a "filters" link to define
new mail filters. When doing so, a new area opens up on the page
between the page heading and the mail listing to allow the user to
define a new filter. This area is created with Ajax, since there is
no page refresh.
I originally presumed that I would be able to create a comparable
capability using the Ajax Updates component, but to do so, would
require that I be able to dynamically reset its size from a line to
an area, or dynamically make it visible and invisible and I see no
way to do either.
If anyone using the WO Ajax support framework knows how to do this, I
would appreciate any help.
Thank,
Jerry
