Hi all, My first post here. I'm currently using a generic Wordpress theme for my website. With limited knowledge of web development, I'm trying to implement a menu that looks like the CanadaGoose website - once a menu item is clicked, the whole website is pushed down and a submenu appears covering the width of the screen. If anyone can shed some light/recommend a plugin that they feel can work, that would be very much appreciated! Thanks in advance.
