I am developing a site based on an original idea.
Users will sort information based on keywords that comes from their own input.
For instance, they might type in "Sports" and will be greeted with search on sports.
However, they can continue to filter the results by typing in "Baseball"
So now their filter will contain "Sports" and "Baseball"
To me, this seems backwards. I currently have very little CSS behind it, so it displays simply as :
sports, baseball
or baseball, sports
depending on the order they typed it in.
Any ideas on best ways to convey to the user how the keywords are working? I.E. filtering down?
