Title: Working with multiple categories
ThreadText: # Working with multiple categories
  
  (Asked by: username_0 on 2016-03-18)
  
  Does anyone know if you can work with `releatedTo` between categories? I’d like to get all the categories in a `categories.group`s that are related to a single category
  
  I have some entries in a channel, lets call it `parts`. The `parts` have two categories from two separate groups.
  
  * Group 1 is `partType` which has the categories `engine` `interior` and `transmission`
  * Group 2 is `manufacturer` which has the categories `ford` and `chrysler`.
  
  On the category-page for `ford`, i’d like to list all the `parts` in the `ford` category, grouped by `partType`
  
  But I don’t wand to show the `partType` categories that have no `parts` by the current `manufacturer`

  I figured it out!
  
  If anyone is stuck at the same place here’s my solution:
  
  ```
  {# category is 'ford' #}
  {% set entries = craft.entries.section('support').relatedTo(category).find() %}
  {% set partsCategories = craft.categories.group('partsGroup').relatedTo(entries) %}
  
  {# Partslist #}
  {% for partsCategory in partsCategories %}
  
      {{partsCategory.title}}
      {% for part in craft.entries.relatedTo([
        'and',
        { targetElement: partsCategory },
        { targetElement: category }
      ]) %}
  
        {{part.title}}
  
      {% endfor %}
  {% endfor %}
  
  ```
