Dropdown Menu

Hi, I’m having trouble with the dropdown menu overlapping other elements on my page. I looked at another thread that had the same issue and it had something to do with the layering, which doesn’t make sense as the whole frame is on top.

And I’m also trying to figure out why every time I press an option, all 3 of my dropdowns go to the selected options as opposed to 3 separate options. I understand that this is a variable problem, but I’m a bit stuck. I have one variable for the state (expanded, default), one for the category (industry, visual type, subject), and I believe I need one more so that each selection stays within its corresponding category after picking an option.
