Hierarchical Select with taxonomy in Views

Question

I have a generic content which can be differencied by a taxonomy term. Then i've created to views filtered by a taxonomy. I want to enable a second filter, exposed , based on the taxonomy, depending on the first filter also bases on the taxonomy but not exposed.

For example: I have the following taxonomy: Type :

1. News
   1. First
   2. Second

2. Publication

   1. Third
   2. Fourth

   My content is 'Article' and the Type is 'News > First' In my View 'News', I can only see the content News ( First or Second), this part is easy. What I need is an exposed filter where i can only choose First or Second from News depending on the fact that I'v already done a previous filter based on the first level of this taxonomy.

How can I do that?

Thanks

You can achieve this by combining Simple Hierarchal Select and Views Dependent Filters. So you use SHS for selecting the taxonomy term, and then set a dependency that if a term is selected on the first taxonomy, show the second taxonomy.

1. Add your first/primary taxonomy that you will be using to determine the secondary options. Don't select any terms, expose filter.
2. Add your secondary taxonomy, expose filter.
3. Add a Global: Dependent Filter to your list of filters.
4. Your Controller Filter is the first taxonomy that will be deciding which second field/taxonomy will showing up.
5. The Controller Values are the values from the taxonomy selected for the Controller Filter. Pick the term which when selected will show the dependent taxonomy. The dependent filter is the secondary taxonomy that you want to show up.

There does need to be some specific ordering going on, like the dependent taxonomy needs to be above the Dependent Filter, but I can't remember exactly. I'm sure you can figure it out from there.
