I would like to group childpages from a parent holder page by date, like discussed in this old topic:

http://www.silverstripe.org/archive/show/15416?start=32

There is some documentation on this page about Dynamic Grouping and DynamicTreeGroup.

http://doc.silverstripe.org/sitetree#dynamic_grouping

Does anyone has an example of how to implement this on a PageType?

And do I read it correct that it is posible to create fake nodes to group certain pagetype in a fake holder with:

class NewsMonthTreeNode extends ViewableData{ //? }

I tried to add add custom children getters like is said here:

http://doc.silverstripe.org/sitetree#custom_children_getters

But I don't really what I chould return there..

Interesting...
