want to create a mobile menu (when screen res smaller)

Hi Currently as im using a sticky menu in both these sites
website 1 - http://tinyurl.com/ozqyopf
website 2 - http://tinyurl.com/plletgb
the menu takes up a lot of space, to condense it i want to make an expanding menu button (normally there is those 3 horizontal lines) but i just came across this . Is it possible to integrate this into both those menu's so that when the screen resolution changes to below a certain number it changes to look like that? (but instead of vertical for it to open out horizontally?)

Opened support access in both domains
