Hi! Thanks a lot! I have updated the theme and departments work good now. But I have other problem: Back to portfolio button does not direct me to parent department. It directs me to my old page that i used as portfolio (it is deleted and does not exist any more). I dont know what to do, maybe problem is on my side. Still trying to find the reason.
I made it with all instructions but it still doesn’t work correctly. I made parent departments Cats and Dogs for example. Then I created two sub depatrtments for Cats and two for Dogs. After that I added parent departments to menu and created portfolio items for sub departments. When I go to menu > Dogs theme shows me dogs and cats together and the same for Cats department. When I click on filters it works fine. You can see it on these screenshots:
