title: WordPress Custom Taxonomies
body: <p>I'm wondering if there's a way to list all custom taxonomies that are siblings to the current page (e.g. in my single.php)?</p>
  
  <p>For example my taxonomy is as follows</p>
  
  <p>Categories</p>
  
  <ul>
  <li>-- Ancient</li>
  <li>+++ Greek</li>
  <li>///// Plato</li>
  <li>///// Socrates</li>
  <li>+++ Roman</li>
  <li>+++ Indian</li>
  <li>-- Classic</li>
  <li>-- Modern</li>
  </ul>
  
  <p>I'd like to create a sidebar that lists all other items that have the same parent (including descendants of other siblings - e.g. "Greek" page would list "Roman" and "Indian". The "Ancient" page would include links to "Ancient >> Greek", "Ancient >> Roman", "Ancient >> Indian", "Classic" and "Modern" Pages. )</p>
  
  <p>Is this possible with custom taxonomies? How can I achieve it?</p>
  
  <p>Thanks!</p>

  <p>Also, for reference, I am working with the following blog posts which give a more detailed insight into what I need, I simply am having trouble customizing it to the specifications I mentioned in my original post: </p>
