Categorys

Hello!

Do this calendar supports categories?
I am looking for a calendar like this; http://sletvoldhuset.no/index.php/kalender-sletvoldhuset/ (This is joomla), to show when rooms are booked or not – and repeating events.. ?

I need a categorysaztion so I can mark the unique rooms with colors.
Can this do that? I cant see any categorysation in the demo.
