Ability to add an "open" psuedo class to the dropdown component (not just the "toggle" and "list")

[samliew (samliew.com)]

There is a CSS open class for the w-dropdown-toggle and w-dropdown-list, but the parent element w-dropdown does not have an open state class when toggled.

Please apply the w--open class to the parent wrapper element w-dropdown as well when the dropdown is open, so that we can target it using custom CSS.

Man! This would be super useful! Thanks for bringing this up - hope we can add something like this soon!

Cheers!
