WP Hide Category

Huseyin Berberoglu

Hides selected categories from lists. You can manage this from your admin panel, so you don’t need to open template 
codes to add exclude parameter to wp_list_categories function. Essentially it adds exclude parameter to wp_list_categories 
function but it’s so easy now. You can manage via admin panel.
