Taxonomy Terms node count of different content type along with zero count in a hierarchy After much headache I was able to maintain a kind of hierarchy for the taxonomy terms, of the already continuing issue here, please click the below link 

Taxonomy Terms node count of different content type

I did It like this, but still needs to do more.

In second step select the parent relation and check the exclude display.


Under format option select the parent taxonomy under group 1



I am getting the parent category under  tag and the child terms as list-terms. using jquery I can display it in an accordion style somehow. 



Now the problem i am facing is that empty taxonomy terms with counter zero are not getting displayed, please help if anyone knows the solution.
Check what you have set for the "no results" behaviour on that field. You will not want it set to "hide".

Also check if it displays in the views preview. If it displays there but not on your page then it may be that your template is checking if a field is blank and before deciding whether to show it - you could solve this by setting a default/no results value of "0"
