I am building a website (www.mpmandco.com) and I am struggling to solve a problem I have on the navigation menu.
The main navigation menu has a submenu with a green background. I want that to be always visible wherever I am within the site. If a sub menu item is active, for example 'About us > Our Goal', that sub menu should remain visible on the green background. When I hover on another menu item, for example Products, the About us submenu must be replaced with the Products submenu.
Hope I explained myself and look forward for your help
