2 dropdown menu

[lem7974]

good afternoon. I'm sorry in advance for my English. I am a newbie and just recently acquired and started studying Pano2VR. I'm trying to make 2 drop-down menus. in the first there should be categories, in the second panoramas corresponding to this category. for example, in the first menu, the first floor category, in the second menu, all panoramas that belong to this category.
I read everything there is about drop-down menus on the forum, I did not meet anything like that.
I would be very grateful if you help me solve this problem
