title: Wordpress - Exclude a category from appearing in menu or sidebar widgets
body: <p>Is there a simple solution (e.g a plugin) for excluding categories appearing in  a menu or sidebar?
  I created a category of posts called "videos" which display youtube videos (naturally!!) but then i realized they were displaying in my "recent posts" sidebar, and i was looking for a simple way to exclude them</p>
  
  <p>Any ideas would be greatly appreciated </p>
  
  <p>Thank you!</p>
