Thanks, but I’m developing a theme and would like to incorporate this feature as a standard.
Is this really that hard to program using a WP_Query or The Loop (in some way)?
If I click a category (ie, ?cat=3), how do I “get” that var? Is the only way to get it through $_GET? And after that, constructing a query that gives me all subcategories of that one, and for each of those, give me all posts.
Does anyone have any ideas about doing that?

The request is ?cat=2, and this code does the trick.
$cat_shown = array();
foreach ($category_cache as $cat_array) {
foreach ($cat_array as $the_category) {
$the_ID = $the_category->cat_ID;
if (in_array($the_ID, $cat_shown))
continue;
$cat_shown[] = $the_ID;
echo $the_category->cat_name;
echo "<br>\n";
}
}
And use $posts to get all posts from cat=2 and sub-categories.

This is exactly what I want to do. Could you explain how this is implemented? Thanks.

You can also use the get_posts template tag to list the posts in a particular category. I found the implementation of this tag to be very easy. http://codex.wordpress.org/Template_Tags/get_posts
I would love to have that option – but I don’t get how I should include the code provided by slidese (Mike). Can somebody please help?!
For what it is worth, I was looking for a way to cycle through categories and list all posts on one page in WordPress MU. I tried Alex King’s Articles Plugin but couldn’t get it to display anything. I ended up combining the post and category queries in a page template. This was pretty simple and works for what I’ve needed so far– I also like that gives me flexibility in what is presented and how it is styled.
I started with the category query using parameters and styling to show empty categories, exclude Uncategorized, and show the category names styled as headers:
<?php
$categories= get_categories('hide_empty=0&exclude=1');
foreach ($categories as $cat) {
$catname = $cat->cat_name;
$catid = $cat->cat_ID;
echo '<h2>'.$catname.'</h2>';
?>
Then I started the post query calling $catid into the parameters and ordering posts alphabetically:
<?php
$posts = query_posts($query_string . 'cat='.$catid.'&orderby=title&order=asc&posts_per_page=-1');
global $more;
// set $more to 0 in order to only get the first part of the post
$more = 0;
// the Loop starts here
if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
After that I formatted the_title and the_content to suit my needs and followed up with
<?php endwhile; else:
_e('There are no posts in this category yet.');
endif;
} //end category query
?>
Not sure that is the best way to do something like this, but I’m adding it here for what it is worth.
