Views and Taxonomy Filtering

Question

I have a question regarding filtering in Views.

My setup:

• I have a content-type, for example: Cars
• I have a few different taxonomy term fields attached to that node, something like: Car brand, Car color, Car type, with the following terms:

• Vocabulary: Car brand
  • Term:Car Brand A
  • Term: Car Brand B
  • Term:Car Brand C
• Vocabulary: Car color
  • Term: Blue
  • Term: Red
  • Term: Black
• Vocabulary: Car type
  • Term: Two seater
  • Term: SUV
  • Term: Sedan

I have a View that displays all the available cars, and I used Better Exposed Filters to display a block that displays those taxonomy fields as filters. Now: this is were I get stuck.

Say for example, that 'Car Brand A' only only sells Blue and Black Sedans. What I would like is that the color option 'red' and car types 'SUV' and 'Two seater' are hidden as selectable option, and re-added if a user selects other brands. How do I do that?

I really hope you can help me with this! :)

Answer 1

If I understand your question correctly, you need the functionality of the Views Selective Filter module.

Although I haven't used this module myself, I've written a similar Views handler in a custom module. This filter handler removes all options from select lists that don't provide any results (due to other selected values). If the Views Selective Filter doesn't provide the desired functionality, I can create a sandbox project of my code.

Answer 2

View's default expose filter didn't give such functionality. You may need the Search API module.

I have seen it in Commerce Kickstart package but didn't use it from fresh setup.
