Describe the issue:

1. Go to https://developer.microsoft.com/en-us/fabric#/components/dropdown
2. Set focus to Basic uncontrolled example DropDown
3. Narrator announces 'Home - Office UI Fabric - Microsoft Edge, Basic dropdown example, editable combo box,'

Expected behavior:

3. It should be a read only combo box. Shouldn't editable combo box have an actual input field that you can type into.

@betrue-final-final What are your thoughts?

[betrue-final-final]

I agree. I meant to comment earlier that it should not be read as editable combo box. @cschlechty on whether 'read-only' means can't type values or can't use. I think this is correct but would love the double verification.

[cschlechty]

aria-readonly means you can't change the value of the control. It looks correct as-is https://www.w3.org/WAI/PF/aria/states_and_properties#aria-readonly

Ok, and "editable" specifically means it can be modified, and not just text editable?

[cschlechty]

yes, i believe so

@satbai According to design this is expected. Closing this issue.
