If I understand the functionality you want, I would render all the content on the page and then hide and show elements of it using jQuery but I'm more comfortable with JavaScript than PHP.

Something like this: http://roshanbh.com.np/examples/exapandable-panel/

Here is the Source

There are more fancy versions of this but this was the first one a quick Google search revealed

Ohh.. I see now. Thank you for clearing that up, zenmonkey.

Here's a jQuery script I use for all my blind-down toggles.

toggle.js

$(function() {
$('.toggle-content').hide();
      $("a[@rel=toggle]").click(
         function() {
            $(this).toggleClass("open");
            $("#toggle-content-" + this.id.replace('toggle-','')).slideToggle("fast");
            return false;
         }
      );
   }
);

Usage:

<a rel="toggle" id="toggle-$ID">Show details</a>
<div id="toggle-content-$ID" class="toggle-content">Some more content here...</div>

Where $ID is a unique number that will be the same on a block of content and its corresponding link.

Maybe the jquery-trick can help, I'll give it a try,

But trying to be a bit more clear. I'm converting a custom-made site (cake-php) to silverstripe, so I can show the current site:
[url]http://www.savedbythebell.be/kaart/provincie/West-Vlaanderen[/url]

This is exactly what I want to reach: a list of schools, and when clicking the name, getting the details,

thanks for your patience

I don't think you'll need jQuery for this. SilverStripe should handle this just fine:
A) place the following code in your ActionPage_Controller class

protected $detailData;

public function details(){
   // get the id parameter
   $id = intval(Director::urlParam('ID'));

   // get the DataObject with the given ID and store it in $detailData
   $this->detailData = DataObject::get_by_id('Action', $id);

   // return empty array, so that the correct templates are being used
   return array();
}

// accessor for the detail data
public function DetailData(){
   return $this->detailData;
}

B) after that, you should be able to call the "details" method, by appending details/id to your page-url, where id is your DataObject ID. Example: http://yoursite.com/your-action-page/details/5
The method will fetch the DataObject with the given ID and assign it to the detailData member-variable. This can then be accessed in the Template using $DetailData.

C) The beauty of this is, that you can use a custom Template (or Layout) file for the details page. Just name it: ActionPage_details.ss. In this template you can then call something like:

<% control DetailData %>
... access all memebers of the Action DataObject here ...
<% end_control %>

There are actually several possible solutions to this problem, this is just one of them (that works for me). I think it's also possible to directly return data to the template renderer by returning some special formatted array (instead of an emtpy one). But the proposed method works equally well.

That's the thing, though. There is no DataObject. The school name is just free text. If it were a has_one relation to school, you could use the /details/$ID approach, but I'm not sure that's what he's looking for.

@banal tnx a lot! This is what I was looking for and worked like a charm.
@UncleCheese maybe it was unclear, but there is a DataObject (Actions), $organisatie was just one argument of it. Tnx for thinking with me.

Hi!

Now that's off-topic, but I tried the toggle.js JavaScript exactly as described by UncleCheese in one of my pages, adding this to Controller:

function init() {
   parent::init();
   Requirements::javascript('jsparty/jquery/jquery.js');
   Requirements::javascript('mysite/javascript/toggle.js');
}

Both files are being loaded, but Firebug says: $(".toggle-content") is null

The class toggle-content is there, as I use the same HTML code as UncleCheese. What can be wrong ?

Thanks in advance,
Juan

I find it myself!

I had to wrap the jQuery code as recommended in http://doc.silverstripe.org/doku.php?id=jquery

;(function($) {
$(document).ready(function() {
   $('.toggle-content').hide();
   $("a[@rel=toggle]").click(
      function() {
         $(this).toggleClass("open");
         $("#toggle-content-" + this.id.replace('toggle-','')).slideToggle("fast");
         return false;
      }
   );
})
})(jQuery);

I would like to know why that worked, since I have already added $(document).ready without success…
