I want to create a product catalog and I have been told that apache SOLR could be the best way to go. I installed Drupal Commerce, Apache SOLR Integration (7.x-1.0-rc2) and Facet API (7.x-1.0). I added a custom field "category" to my product display content type which refers to a hierarchical taxonomy vocabulary.

  • Clothing
    • Tops
    • Dresses
    • Skirts
  • Accessories
    • Bags
    • Jewelery
  • Shoes
    • Pumps
    • Sneakers

On my products page I would like to see a facet block where I can select my categories. I want to show my top level categories without their children at first, but when you select a category I also want to see its' children. You can achieve this functionality with the standard installation I believe.

BUT when I select one top level category (Clothing) my other top level categories disappear (Accessories, Shoes). I don't want to be able to select multiple top level categories at once, I just want them to be visible...
Is that possible in any way?

Although I've not tried the recipe I believe that this article over at wunderkraut is an exact match for what you are after. There is a lot of custom coding involved.
