Dear Dimitar!
thanks for information. I had a closer look at the customviews. They offer some flexibility ... but I'm not sure whether they could solve my problem finally. The requierement is to show three levels:
* year
* month
* calendar week
Year and month is easy, but the calendar week seems to be a challenge concerning the layout. The count of weeks of a year could differ - 54 or 53. And the count of weeks per month is not always the same. Any ideas about how to solve that?
Best Regards!
