I don't think I am understanding your use-case. If the field is required, you shouldn't have any empty option right?
dephiros commentedon Nov 13, 2016
The requirement that I have designing the form is all select should have the an empty option to clear the select after user selecting a valid value. We just use this as the standard select across everywhere in the application regardless if the field is required or not

I guess if you're attempting to use these together, it does seem like the
md-option-emptyshould indeed reset the validity of the model. However, I'll leave this to @ThomasBurleson's judgement as to whether or not this should be considered a bug.[-]mdSelect: form remains valid after deselect a required md-select with empty option [/-][+]select: form remains valid in a required md-select when empty option is selected[/+]Splaktar commentedon Aug 26, 2019
This updated CodePen demonstrates how this is still an issue in
1.1.20in addition to providing a side-by-side comparison to a regularselectwith AngularJS. This certainly seems like a bug that needs to be fixed.Reference: https://stackoverflow.com/questions/12654631/why-does-angularjs-include-an-empty-option-in-select
