Widget API pops up behind other elements

Hi guys,

I embedded a reservation API for this restaurant website I created. It works fine, except for the fact that it pops up behind other elements (on this specific page behind the footer) and I can’t figure out how to get it to the front. I tried different positioning, playing with the z-index and placing it inside a div but nothing seems to work. Any help?
