You can change menu type from categories to custom menu. In this case, you can specify unique CSS class to each top menu item:

found the solution and posting it for others who might have the same problem.. first made the custom css like the print screen that eComLabs posted

and then added the css

.ty-menu-item_get_inspired ul.ty-menu__submenu-items {
width:550px;
}
