I'm trying to customise Bootstrap 4 navbar and its contents...my task is to add more nav items on drop down menu. the problems comes when i wrap container fluid elements in drop down items with its default CSS style (position absolute) the container fluid elements loses layout on large screen size .
I will be grateful for any help you can provide to fix my code
