Disable float for mdInput text field

As per version 6.4.5 of @angular/material2 you can control floating labels using floatLabel input property as you can see in their floating label documentation.

<mat-form-field [floatLabel]="'never'">

<md-input-container [floatPlaceholder]="'never'">

this helped me to hide the floating placeholder

Edit: Since Angular Material 6

<mat-form-field floatPlaceholder="never">
