Website does not respond to click

hi guys,

my problem is the two lists. I want to click them one after the other click1 and click2 to be able to scrape all variations. I have now tried with one click, but it does not click on the different buttons. Did I choose the wrong elements or is it the website?

Thanks a lot in advance!
