I asked this question before and was supplied with some code but I can't seem to locate my original question on the forum. Anyway, I can explain again here.
I am trying to implement some more question filters to the Q&A plugin. In my original question I used stackoverflow as an example of what I was trying to achieve.
To Sum Up.
In the top level filters it would be nice to have a "Tags" - "Users" - "Categories" filter up there.
I was also interested about sub-filtering (not sure how best to describe this) but when I click questions, I then can filter the questions themselves by "Votes" - "Newest"
I guess all the date is there from the questions it is just a matter of how to filter it on the frontend.
I was supplied with this code snippet to get it working but it did not work. I was hoping to re-visit this topic and get some more guidance on it.
Code Snippet you provided me last time was http://pastie.org/4288543
