Iframes on CMS Pages stops tabs, the footer & Drop down menus from working

I wanted to add Amazon buy now buttons (they are Iframes) to my cocktail recipes page in a “buy on amazon” however when I done this all tabs, drop down menus stopped working & my footer element just doesn’t show up.

I have tried moving the iframes outside the tabs but it still has the same problem If I have an iframe on the CMS Page.

Is there a fix for this?
