Multicolumn Flyout Menu or SubMenu with Dividers

I’m trying to make the menu on my website look like the mega menu on trex.com when you hover over “Start Your Project”. It has dividers between the columns which I really want. Could you point out which tutorials would be applicable to do this or let me know what to do in detail? I’m not sure how to do any of the styling for the columns or the dividers and I do have the pro version of mega menu.
