Isotope Search breaks dropdown

Hi. I’m having some problems with my Isotope Search Filter. I manage it to work (on several websites) but I’m having problems with one. On this website, the CMS-item has a dropdown to show the information, and (I think) this is causing the issue. The problem is that when I open the dropdown the items below don’t get pushed down. When I disable the Iso-code the dropdown workers.

Here is my public share link: LINK
