Related to this is the question, if I have the following structure
cat1.1
cat1.2
cat2.1
cat2.10
cat2.2
cat3.4
cat4.5
and I want to order by the second level (1,2,10 ...), though within the first level (cat1, cat2 ..) where the ordering of the first level is given, e.g. I want to say.
Order me all pages which by page_order, where the category order is "cat2 cat3 cat1 cat4"
This should return:
cat2.1
cat2.2
cat2.10
cat3.4
cat1.1
cat1.2
cat4.5
Any clue how I could do this ?
