danielebarchiesi@0: In Views areas (header, footer, empty-text) are pluggable, this means you can write your own php logic to place whatever you want.

danielebarchiesi@0: <h3>Requirements</h3>
danielebarchiesi@0: 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
danielebarchiesi@0: how to extend views.
danielebarchiesi@0: 
danielebarchiesi@0: <h3>Create your own area handler</h3>
danielebarchiesi@0: 
danielebarchiesi@0: The first step is to tell views: Hey i want to add a new area handler.
danielebarchiesi@0: Therefore you have to implement hook_views_data and add a new one. For example:
danielebarchiesi@0: 
danielebarchiesi@0: <pre>
danielebarchiesi@0: function yourmodule_views_data() {
danielebarchiesi@0:   $data['views']['collapsible_area'] = array(
danielebarchiesi@0:     'title' =&gt; t('Collabsible Text area'),
danielebarchiesi@0:     'help' =&gt; t('Provide collabsible markup text for the area.'),
danielebarchiesi@0:     'area' =&gt; array(
danielebarchiesi@0:       'handler' =&gt; 'yourmodule_handler_collapsible_area_text',
danielebarchiesi@0:     ),
danielebarchiesi@0:   );
danielebarchiesi@0: }
danielebarchiesi@0: </pre>
danielebarchiesi@0: 
danielebarchiesi@0: The second step is to write this handler. Therefore create a file called yourmodule_handler_collapsible_area_text.inc and
danielebarchiesi@0: add it to the .info file of your module.
danielebarchiesi@0: 
danielebarchiesi@0: Then add content to your area file like this:
danielebarchiesi@0: <pre>
danielebarchiesi@0: class yourmodule_handler_collapsible_area_text extends views_handler_area_text {
danielebarchiesi@0:   function render($empty = FALSE) {
danielebarchiesi@0:     // Here you just return a string of your content you want.
danielebarchiesi@0:     if ($render = parent::render($empty)) {
danielebarchiesi@0:       $element = array(
danielebarchiesi@0:         '#type' =&gt; 'fieldset',
danielebarchiesi@0:         '#title' =&gt; t('Title'),
danielebarchiesi@0:         '#value' =&gt; $render,
danielebarchiesi@0:       );
danielebarchiesi@0:       $output = theme('fieldset', $element);
danielebarchiesi@0:       return $output;
danielebarchiesi@0:     }
danielebarchiesi@0:   }
danielebarchiesi@0: }
danielebarchiesi@0: </pre>
danielebarchiesi@0: 
danielebarchiesi@0: 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 :)
