Footer expandable menu in mobile view?

[MDKSocks]

Hi guys,

I just did some tweaking with my footer and the desktop version is exactly how I want it. But the mobile version is way to long if you ask me... (see www.mdksocks.nl).

Is it possible that you make some kind of expandable menu of the footer like this website has for instance:

 That way you can expand what you want and make the site smaller. I don't like it that the footer is almost as long as the rest of the website in mobile view.

Is there an easy way to do this?

I think I posted it on a wrong time so I hope that someone has an answer for me
