customise shopify store to be able to filter products by multi dropdown lists

I have a shopify store, I want to add to the header multi dropdown boxes: 1- from the first, the user chooses an attribute like a year 2- from the second, the user choose another attribute like category 3- from the third, the user choose another attribute like sub-category then the products which are related to the 3 dropdown values are shown. Notes: -i user can select just 1 value from 1 dropdown, or 2 or 3 together. -ii dropdown values will be changed by the value of another dropdown example of what I want to achieve:[login to view URL] working scenario: - user selects the year from the first then the car type from the second, then the car brand from the third, and the cars appear. I don't want to use apps that require a monthly subscription. waiting for your bids including the demo you have for a working scenario
