Angular Material md-select default selected value

Question

I am using Angular 2 with Angular Material. Looking at the documentation, I am trying to get the select to have a default value as oppose to an empty place holder.

I have tried the following two options and both of them does not set a default value

<md-select selected="1">   <md-option value="1" >One</md-option>   <md-option value="2">Two</md-option> </md-select>  <md-select>   <md-option value="1" selected="true">One</md-option>   <md-option value="2">Two</md-option> </md-select> 

I looked at all the documentations and the examples, non of them helped

Answer 1

Use [(ngModel)]:

<mat-select [(ngModel)]="selectedOption">   <mat-option value="1">One</mat-option>   <mat-option value="2">Two</mat-option> </mat-select> 

Component:

selectedOption = '1';

Edit #1:

Since Material2.0.0#beta10 (specifically this PR) you can select a value using the value property of MatSelect:

<mat-select [value]="selectedOption">   <mat-option value="1">One</mat-option>   <mat-option value="2">Two</mat-option> </mat-select> 

Component:

selectedOption = '1';

Note that you can also use it with two-way data binding -> [(value)].

Answer 2

 <mat-select [value]="0" >

We can easily do it using setting value to default value
