Don't override Date in the example

[Owen Masback]

This tripped me up for a second. I was trying to use js native Date in my code but it had been reassigned to the component class because i copied the example code. Maybe assign the import to DropdownDate or something else

It's a default export, so you can have your own name to it
eg:
import SomeDate from 'react-dropdown-date';
import DropdownDate from 'react-dropdown-date';

Fixed it in ReadMe though.

Thanks
