md input container throwing error when I put input tags as child

Question

Trying to use the following code from the Angular examples page:

 <md-input-container>
    <label>Vegetables</label>
    <md-select ng-model="selectedVegetables"
               md-on-close="clearSearchTerm()"
               data-md-container-class="selectdemoSelectHeader"
               multiple>
      <md-select-header class="demo-select-header">
        <input ng-model="searchTerm"
               type="search"
               placeholder="Search for a vegetable.."
               class="demo-header-searchbox md-text">
      </md-select-header>
      <md-optgroup label="vegetables">
        <md-option ng-value="vegetable" ng-repeat="vegetable in vegetables |
          filter:searchTerm">{{vegetable}}</md-option>
      </md-optgroup>
    </md-select>
  </md-input-container>

But this is the error I get:

Error: can only have one child input, textarea or select element!

The example can be found here (look for Select Header): https://material.angularjs.org/latest/demo/select

Well as i said on the comments the problem was the version of your Angular-material

Try to update it to the lastest version 1.0.9 or 1.1.0 and make a try.

<!-- Angular Material Library -->
<script src="http://ajax.googleapis.com/ajax/libs/angular_material/1.1.0/angular-material.min.js">
