View showing ONLY taxonomy children terms and NO parents I've managed to got my view working but my worry is that this method is not dynamic. 

What I want to achieve?
To have a list of articles tagged with terms that are one level deep (children) but not their parent terms.

E.g.: assuming a taxonomy looks like this:

A 
  A1
  A2
B
  B1
  B2


I want to be able to go to the URL mysite.com/A/A1 or mysite.com/B/B2 and retrieve a list of articles with ONLY content tagged with A1 or B2 (in this example)

For that I added a filter and manually selected the parent terms I don't want to list:



Is there a better solution to achieve this?

Thanks!
Super simple but impossible to guess solution : 

With a normal filter set the "Parent term" filter not equal to "0".

This will filter parents
