[Dropdown] - Add ability to clear selected value with (x)

[zelenin]

Empty options are removed. I cannot reset filter selecting empty option.

Empty string values '' were designed around being placeholder values not actual selectable values.

I would recommend using a different value if possible, for example no value.

It would also make sense to have clearable as an option. But this might take a while.

Oh, I understand it but I think that it's very-very-very big hack using empty value for placeholder generation. You must understand it.
There is no case for clear selected value. There is case about not-full support of native selects.
I think its behavior should be changed.

This is the same setup select2 uses. I think its alright

[zelenin]

no, select2 not use it.

example:

It changes standard behaviour of select. It's cannot alright.
