   Hello,

   I am using wp_list_categories to make my site navigation, both an upper bar and a lower bar with the children if they exist.

   I want to highlight the current category and at first I was using the built-in class that WordPress assigns, but then I wanted to get it to work even in single (post) view, so I used this:

   <?php
   	if  (!is_page() && !is_home() && !is_single()){
   	$catsy = get_the_category();
   	$myCat = $catsy->cat_ID;
   	$currentcategory = '&current_category='.$myCat;
   }
   
   	elseif (is_single()){
   	$catsy = get_the_category();
   	$myCat = $catsy[0]->cat_ID;
   	$currentcategory = '&current_category='.$myCat;
   }
   
   	wp_list_categories('depth=1&title_li=&orderby=id&exclude=1,5,6,19,20,21,22&hide_empty=0'.$currentcategory);
   	?>

   Which works great if the post is only categorized in one category...if you have it in several, it seems to highlight only the first alphabetical category.

   How can I make this more robust?

   To be more specific for my case: I am excluding certain categories (see above code) and if one of those comes before a category I am using, nothing gets the active class (because it only gives it to the first one, alphabetically).

   I would be interested in highlighting all the categories the post falls into, or even just having it skip the categories I am excluding from the navigation...then at least one navbar item would get the active class for each post (for visual consistency).

   Thanks!

   I'm working on a somewhat similar problem, but didn't come up with a solution yet.
   I thought about modifying the wordpress core-files and extending the native function that assigns the "current-cat"-class to the active category on archive pages as well to the post, but it obviously isn't within the category-template.php and I have no clue where else to look.

   @signyourbikeout,

   I was looking to fix this as well and came across this tutorial which then linked to this plugin.

   Instead of running the plugin (it's just one function), I added it to my functions.php and now I get a current class for a category even when on a single page. Not sure if it works when having more than one level of categories, but might be worth giving it a try.

   Hi karl19,

   Thanks, yeah I did actually end up coming across that post and using it on my site. It works for single.php, but does not handle multiple categories very well. I have a function in place now that seems to handle it 'most' of the time.

   Not 100% amazing, but doesn't cause any errors and half the time adds the active class to multiple parents plus one child

   I found this "Kahi’s Highlight Used Categories" plugin to be of great help. Handles multiple categories perfectly.

   Make sure you add a .used-cat class in your style.css to behave similarly as the .current-cat class provided by wordpress.
