How do I display taxonomy child terms? I used the Taxonomy View Depth module to create a taxonomy vocabulary like this. 

Animal


Cats


Brown
white

Dogs


Brown
White



What I did was enabling the default taxonomy view, and changing the depth in Content: Has taxonomy term ID (with depth) to 1 instead of 0 (also tried 2,3, etc.)

The children items will never show on the page. It does remove the There is currently no content classified with this term. from the page.

What I want? With Taxonomy menu I want to be able to click Cats and show the second level children.
I used View tree Module to achieve this same kind of functionality but i used it for Node Reference. As per their module page, this module is also compatible for taxonomy.

Here are the steps to set Views Tree to display hierarchical taxonomy.

Create a new term view using the fields row style


add relationship for taxonomy term: parent term
add field term id (do not use relationship) and exclude it from display
add field term id with relationship, exclude from display
add any fields you want to display, like term name, term description, etc...
Change style plugin to Tree (Adjacency model)
Set Main field to Term ID
Set Parent field to Term ID with parent relationship
