TOPIC: Multiple categories in calendar

Hi!

Is it possible to choose multiple categories in the calendar view?

Now I have like this in DT Register:

Colors (main category)
- Red (sub)
- Green (sub)
- Blue (sub)

When I view "Colors" in calendar view all the subcategories should be there, now it's just empty. Or am I missing something else?

At this time you can only choose one category to filter the calendar at a time.
