'md-option' is not a known element

Bug, feature request, or proposal:

Bug (or wrong usage?)

What is the expected behavior?

Options should be displayed within the select element.

What is the current behavior?

The whole application does not render

What are the steps to reproduce?

Tried to reproduce it with a plunkr, was happy when i edited your template and saw i got the same error. after opening and verifying it in a new private window the error disappeared. So i assumed it could be a client cache problem, but after retrying with different browsers i still get not managed this problem.

Which versions of Angular, Material, OS, browsers are affected?

I am using Material 2.0.0-alpha.11-3 with Angular 2.2.4

Is there anything else we should know?

I am using Angular-CLI

Started working after adding import { MaterialModule } from ‘@angular/material’; import { MdSelectModule } from ‘@angular/material’;

and importing it to array like below on the same module as where the form is. If added to app.module.ts it was still giving error

imports: [ BrowserModule, FormsModule, HttpModule, MaterialModule, MdSelectModule ],

I had to import the MdSelectModule separate to the MaterialModule to get it to work.
