Angular Material: how to set floatPlaceholder to never

You can set the floatPlaceholder input to: auto, always, never.

<md-input-container floatPlaceholder="never">
          <input type="text"
                 mdInput
                 placeholder="Search...">
</md-input-container>

---

Update (Angular Material 6):

Now you have to use floatLabel:

<mat-form-field floatLabel="never">
    <input matInput placeholder="Search...">
</mat-form-field>
