Taxonomy Term Hierarchy(not programmatically nor content related) I know there are zillion topics about this, but I just couldn't apply it to my View Block in Drupal 8. On the other hand all these Taxonomy Term Tree creation is based on content related. 

Here is what I would like to do, I would like to display my "Collections" taxonomy term hierarchy without content relationship, as it is(just parent-child terms). This is how my taxonomy term hierarchy looks like:



And this is how far I could get:



This is my result(which is completely wrong):



**FYI: I am using Views Tree and I follow this Taxonomy display children with Taxonomy View Depth not working **

Thank you for help and time in advanced.
you can use the Views Tree module for this: https://www.drupal.org/project/views_tree

It works pretty well, you just need to use the Tree (list) views FORMAT, add the parent taxonomy term in RELATIONSHIPS, add the parent term's Name field to the FIELDS list, and then use it as the Parent field on the Tree settings:



The module will link the terms hierarchically and output a nested list, and you can always hide the parent term's name field to show just the children terms names.
