Category cloud can be added by using the taxonomy argument to cause a cloud of categories to display. You can either modify wp-content/yourtheme/single.php from ssh or using ftp OR you can login to wordpress dashboard, and go to “Appearance -> Editor -> ad click “single.php” Post below line, <?php wp_tag_cloud( array( 'taxonomy' => 'category' ) ); ?> After, <div class="thecontent"> <?php the_content(); ?> </div> So, the final change could look like as below, <div class="thecontent"> <?php the_content(); ?> </div> <?php wp_tag_cloud( array( 'taxonomy' => 'category' ) ); ?> To update into single page, modify the page.php as above. If we want to customise the look of default Category cloud, we can modify the following code from wp-includes/category-template.php to add a border , and fill the color with boxed looks as below, // Generate the output links array.
