Help, code for interactive cookie bar with preferences!

Hi all,

For my landingspage I need a interactive cookie pop up with checkboxes that can then update preferences based on selections on the form. I’ve asked Unbounce but they suggested that I needed a Developer. I do have some code skills but this kind off surpasses me.

So I was wondering, had anyone tried this already? If yes, is there a existing code I can use? Thank you in advance! here is a picture as reference:

Hi Brenda,
what if you pick something that is available on the market?

Actually, the url is and it looks like a great solution.
