   hi,

   i'm trying to use the categories as a navigation. So far i got the subcategories showing nicely when on a parent or sibbling in the sidebar using this code:

   <?php
   if(is_category()) {
   
   	$breakpoint = 0;
   	$thiscat = get_term( get_query_var('cat') , 'category' );
   	$subcategories = get_terms( 'category' , 'parent='.get_query_var('cat') );
   
   	if(empty($subcategories) && $thiscat->parent != 0) {
   		$subcategories = get_terms( 'category' , 'parent='.$thiscat->parent.'' );
   	}
   
   	$items='';
   	if(!empty($subcategories)) {
   		foreach($subcategories as $subcat) {
   			if($thiscat->term_id == $subcat->term_id) $current = ' current-cat'; else $current = '';
   			$items .= '
   			<li class="cat-item cat-item-'.$subcat->term_id.$current.'">
   				<a href="'.get_category_link( $subcat->term_id ).'" title="'.$subcat->description.'">'.$subcat->name.'</a>
   			</li>';
   		}
   		echo "<ul>$items</ul>";
   	}
   	unset($subcategories,$subcat,$thiscat,$items);
   }
   ?>

   which I got from this thread: http://wordpress.org/support/topic/showing-subcategories-of-a-parent-page-under-subcategory

   big thanks to t31os_ !

   my problem now is that the subcategories still need to show when viewing the individual posts. tried the code from akis but it doesn't work for me.

   quite new to this so pl keep answers simple, thanks!

   <?php
   
   	$breakpoint = 0;
   	$thiscat = get_term( get_query_var('cat') , 'category' );
   	$subcategories = get_terms( 'category' , 'parent='.get_query_var('cat') );
   
   	if(empty($subcategories) && $thiscat->parent != 0) {
   		$subcategories = get_terms( 'category' , 'parent='.$thiscat->parent.'' );
   	}
   
   	$items='';
   	if(!empty($subcategories)) {
   		foreach($subcategories as $subcat) {
   			if($thiscat->term_id == $subcat->term_id) $current = ' current-cat'; else $current = '';
   			$items .= '
   			<li class="cat-item cat-item-'.$subcat->term_id.$current.'">
   				<a href="'.get_category_link( $subcat->term_id ).'" title="'.$subcat->description.'">'.$subcat->name.'</a>
   			</li>';
   		}
   		echo "<ul>$items</ul>";
   	}
   	unset($subcategories,$subcat,$thiscat,$items);
   
   ?>

   or uses if(is_category() || is_single()) instead of if(is_category())

    and the siblings of that subcategory.

    I got the categories in my main nav, then when selected the specific subcategories show in the sidebar, and I want them to stay that way when viewing the posts belonging to any of those subcategories
