28 Sep 20236 minutes to read

The Floating Label TextBox floats label above the TextBox after focusing, or entering a value in the TextBox.

Floating label supports the types of actions as given below.

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

Import the Input modules from ej2-inputs library as shown in below.
```
import {Input} from '@syncfusion/ej2-inputs';
```
Pass the HTML Input element and floatLabelType property as Auto to the createInput method.
Set the placeholder value to the input element via element attribute or pass the parameter to the createInput method.

The watermark label will be updated based on the specified placeholder value of the Floating Label TextBox.

You can add the icons on the input by passing buttons property value with the class name e-input-group-icon as parameter to the createInput method.
