   1 In Views areas (header, footer, empty-text) are pluggable, this means you can write your own php logic to place whatever you want.

   3 <h3>Requirements</h3>
   4 You should have read <a href="topic:views/api">API</a> and <a href="topic:views/api-tables">Tables API</a> to get a basic knowledge
   5 how to extend views.

   7 <h3>Create your own area handler</h3>
   8
   9 The first step is to tell views: Hey i want to add a new area handler.
  10 Therefore you have to implement hook_views_data and add a new one. For example:
  11
  12 <pre>
  13 function yourmodule_views_data() {
  14   $data['views']['collapsible_area'] = array(
  15     'title' =&gt; t('Collabsible Text area'),
  16     'help' =&gt; t('Provide collabsible markup text for the area.'),
  17     'area' =&gt; array(
  18       'handler' =&gt; 'yourmodule_handler_collapsible_area_text',
  19     ),
  20   );
  21 }
  22 </pre>
  23
  24 The second step is to write this handler. Therefore create a file called yourmodule_handler_collapsible_area_text.inc and
  25 add it to the .info file of your module.
  26
  27 Then add content to your area file like this:
  28 <pre>
  29 class yourmodule_handler_collapsible_area_text extends views_handler_area_text {
  30   function render($empty = FALSE) {
  31     // Here you just return a string of your content you want.
  32     if ($render = parent::render($empty)) {
  33       $element = array(
  34         '#type' =&gt; 'fieldset',
  35         '#title' =&gt; t('Title'),
  36         '#value' =&gt; $render,
  37       );
  38       $output = theme('fieldset', $element);
  39       return $output;
  40     }
  41   }
  42 }
  43 </pre>
  44
  45 As on every handler you can add options so you can configure the behavior. If the area isn't shown yet in the views interface, please clear the cache :)
