Demo Cafe

1.) Hello, i would like to know how can i change the demo cafe menu - same like the demo-burger menu?
i mean to have it mouseover the menu item, i haven't tried anything yet so i ask here for a clear explanation on how to do it.

2.) How to change the menu in the demo cafe same like using the dotted menu on the right? I don't want to use a link that goes to one page to another page, just in 1 page in Demo Cafe.

P/s: I don't have the live url yet.

Thank you in Advance.
