title: Wordpress - Custom post type "all posts" listing taxonomies
body: <p>I've created a custom post type with several taxonomies.
  The thing is that's listing all taxonomies in the custom post type's listing page (All pages button) and I would like to choose which ones to display and which ones not. 
  Googled a lot, but can't find a way to solve this.</p>
  
  <p>Anyone knows wich functions/flags are necesary to let wordpress know if I want X taxonomy to be shown in the listing page of the  custom post it's related to?</p>
  
  <p>Sorry if I don't add any code, I believe it's not necesary since it's a teorical question.</p>
  
  <p>Thanks in advance!</p>
