It is possible to allow Views to show only content that has child terms from a taxonomy?
Yes, it is. This is similar but slightly different to our tutorial on using Views to show only child terms.
First, you need to have your site set up correctly. You will need:
- A taxonomy that has parent and child terms, as in this example below.
- A content type that uses this taxonomy as a "Term reference" field.
- Content that is tagged with these taxonomy terms.
Let's show you how to set up Views so that only content with child terms. In this example, the content needs terms such as Amphibians, Birds, Fish, Mammals, Reptiles.
- Go to Structure > Views > Add new view.
- Create a View that shows Content of the type that you want to show:
- Click "Add" next to Relationships.
- Search for "Content: Taxonomy terms on node":
- Choose your taxonomy.
- Click "Apply (All displays)" to save your relationship.
- Click "Add" next to Filter Criteria.
- Search for "Taxonomy term: Parent term".
- Click "Apply (All displays)".
Now the "Value" in this next step the key to the process.
- The top level taxonomy terms have a value 0.
- The second level terms have a value of 1.
- The third level terms have a value of 2 etc.
This tutorial on Delta in Drupal explains more.
So if we want to ignore the parent terms, we choose "Is greater than or equal to" and then enter a "Value" of 1.
- Save the filter and save your view.
- You should now see that the parent terms are ignored:
