Expand all subpages – is that possible?

Have a look at the Fold Pages plugin/widget:

Thanks. That’s not quite what I wanted: I need a plugin that EXPANDS (=INSERTS) the actual content of the subpages in the parent pages. The idea is is as follows: I have a topic in a static page with a number of subtopics. When the user clicks on the page, I want him/her to see all the subpages wo he/she can read all the info in one go without having to click on any more links…

Ah! I used the following code inside the Loop within a customised template to achieve a similar effect:

<?php
$my_slug = get_permalink();
$args = array(
	'numberposts' => -1,
	'post_parent' => $post->ID,
	'post_type' => 'page',
	'post_status' => 'publish',
	'orderby' => 'menu_order,title',
	'order' => 'ASC'
);
$my_pagelist = &amp;get_children($args);
if ($my_pagelist) :
foreach($my_pagelist as $my_child) :
$my_child_slug = $my_slug.$my_child->post_name.'/';
?>
<div class="sub_page">
<h3><?php echo $my_child->post_title;?></h3>
<?php echo $my_child->post_content; ?>
</div>
<?php endforeach; ?>
<?php endif; ?>

I then assigned the new template to the parent Page(s) as required. Just remember to changed the encoded ampersands above into a plain &.

Hope that helps.
