How could I collapse/expand elements from online ordering iframe?

I want to expand or collapse the restaurants order menus (highlighted in yellow) depending on user input, how it is possible to reference iframe elements with javascript?


Currently Corvid is not integrated with Wix Restaurants yet. It is currently not possible to reach the ID of the elements within the iFrame of the app. At Wix, we are continuously working to improve and update existing features and introduce new ones. The latest Corvid updates can be found here and the current Corvid Wishlist here . You can find the current features in development here or request this feature here .

Best regards,

Even not possible with some HTML/JS “hacking”?
