Setting the floatlabel type

You can use the floatLabelType property to display a floating label above the input element. This will work when a placeholder is used.

You can change the floatLabelType type to Never, Always, Auto.

Never: The label will never float in the input when the placeholder is available.
Always: The floating label will always float above the input.
Auto: The floating label will float above the input after focusing or entering a value in the input.

The following example shows the floatLabelType with Auto
