Disable validation for specific input fields of a form

[TimmWerner]

I have several input forms where I don't want bootstrap to highlight all input fields on validation.
Marking the invalid inputs is fine, but marking every other input as correct (with green border, checkmark etc.) is not what I want sometimes.

For example a select/dropdown that can't even have a wrong input, should not be marked as correct.

So it would be nice to have a class like .no-validation to mark inputs that should not be visually highlighted as correct on validation.
