How to implement menu in material style?

Question

css

I am developing a service and sticking to the design material, there was a hitch with the implementation of the menu, I want it exactly like on the Google site!

Help me find the implementation on css/js
update
It's a little bit different, we need to go over the entire site and darken the rest of the area
