Let me see if I can explain what I need.
1) I need some tabbed buttons listed first:
View All | Category 1 | Category 2 | Category 3
2) For each button, clicking the tab should opens an area to display:
Other tabbed buttons (to the left).
Current | Future | Past
Each of the buttons/views has a grid and a table display each (to the right).
Grid | List
Those are all views (example: Category 1 - Current - Grid format view, Category 1 - Current - Table format view).
I can probably use quicktabs module to display my top level tabs, but how to achieve #2?
