### Steps to Reproduce
When using a DateDropInput component, I am trying to disable when certain conditions have been met. When I attempt to set inputProps={{disabled: true}} to see if this would work. The field is still enabled and I can still select dates.

### Expected Results
I am expecting that the specific date drop component I am rendering will be disabled when I set the conditions for disabled.

### Actual Results
The date drop input is still enabled
