Option to have white dropdowns and stuff

[ivangretsky]

Good day!

Just one more time want to say, that the theme is beautiful! When upgrading from 5.5. to 6.3 the top nav dropdowns and a number of other elements became colored instead of just white. We are so used to white dropdowns and the whole "clean" look of the previous version)) Could you consider adding an option to have the old styles with mostly white backgrounds?

Thank you!
