I found a way that works well and hope others find this useful. First make a copy of category.php and put it in your child theme folder. Name it “category-xxx.php” – where xxx is the slug name of the category (or number). Then, replace this part of the code:
<?php /* Start the Loop */ ?>
<?php while ( have_posts() ) : the_post(); ?>
<?php
/* Include the Post-Format-specific template for the content.
* If you want to overload this in a child theme then include a file
* called content-___.php (where ___ is the Post Format name) and that will be used instead.
*/
get_template_part( 'content', get_post_format() );
?>
<?php endwhile; ?>
<?php twentyeleven_content_nav( 'nav-below' ); ?>
<?php else : ?>
<article id="post-0" class="post no-results not-found">
<header class="entry-header">
<h1 class="entry-title"><?php _e( 'Nothing Found', 'twentyeleven' ); ?></h1>
</header><!-- .entry-header -->
<div class="entry-content">
<p><?php _e( 'Apologies, but no results were found for the requested archive. Perhaps searching will help find a related post.', 'twentyeleven' ); ?></p>
<?php get_search_form(); ?>
</div><!-- .entry-content -->
</article><!-- #post-0 -->
<?php endif; ?>
with this:
<?php /* Start the Loop */ ?>
<ul class="category">
<?php $archive_query = new WP_Query('cat=25&showposts=1000');
while ($archive_query->have_posts()) : $archive_query->the_post(); ?>
<li><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></li>
<?php endwhile; ?>
And set ‘cat=25’ to the id number of your category. You will end up with a bulleted list of only the titles on your category or subcategory page.
