Is it possible to have portfolio sub-categories for portfolio grid pages? I'll use an example to show what I'm trying to accomplish:
Let's say I have a portfolio called "Work samples" which houses two sub-portfolios called "Photos" and "Other". The main page has a portfolio carousel for "Work Samples" (thus it would show Photos and Other as its two slides). When a user click on Photos, i'd like him to have an option of selecting further "portfolios" which are classified as Photos (say, "Landscape" and "Portrait"). When clicking on "Landscape", the user would then see all the "Landscape" photos.
I've tried assigning "Parent" categories to the portfolios, but that doesn't seem to have worked, as the "Work Samples" carousel keeps capturing the "Landscape" and "Portrait" links as well.
Am I missing something?
