I working with a parent category, and we call these category "colors", this category have two child categories we named here childcategory "red" and another childcategory "blue".
When i go to the category page i see both child categories but mixed up, this is the result of the date where posts in the childcategories are made.
My problem is i have to make the category "colors" where the posts are sorted in two blocks, first all the posts of childcategory red (with content) and thereafter the posts of childcategory blue (with content) also each block should be sorted to the date they made. if a post is made in childcategory red today and at the same day a post is made in childcategory blue they chould be present in their own blocks not the one after the other...
