When I spoke filters meant categories, I am sending a layout to better identify what I mean by the “filters” (categories).

Which leaves me more confused is the fact of having to make a gallery only for photos and one only for video, and the two must be categories.

Can you understand? If there is any problem of understanding I can make an illustration.

I hope you can help me!
