Your question is not clear enough. Menu item menu leads to the page with the products. Do you want to change products themselves? If yes, how, or you would like to add them as a mega menu?
No, see attachment screen shot of the Menu how it looks right now.
You can see the picture of the TV Screen, that’s the issue.
I would like to remove it and use an another picture (Bracelet) which match my new menu category.
