Help - Creating full width drop down mega menus

Hi guys,

Can anyone help me out with my nav menus. I’ve set them up as they are at the moment just to get them working.

Ideally I want to change them so that they are full width and I can drop an image next to each item using the product thumbnail to show what they look like.

I know I’m missing something and can’t work it out myself at the moment so hoping someone has the answer!
