Make Menu as Walmart’s menu

Hello!
i’ve been searching around for a plugin that helps me make my current menu on my website to have the same functionality as the walmarts.com website on desktop view.

So far i have not found any plugin that helps me achieve this.

I wondering if i could maybe mess up the code a bit in order to do it by my self but im affraid to do it. Any suggestion if really appreciated.

thanks in advanced.
