Add floating label to TextBox programmatically in React TextBox component

21 Feb 202611 minutes to read

The floating label automatically floats above the TextBox input field when the user focuses on it or enters a value. This behavior enhances the visual hierarchy and provides clear input context. Configure the floating label behavior using the floatLabelType property with the following options:

Type	Description
Auto	The label floats above the input when focused or when a value is entered
Always	The label always remains floating above the input
Never	The label never floats; placeholder text is displayed instead (default behavior)

Implementation steps

1. Import the Input module from the ej2-inputs library:

    import {Input} from '@syncfusion/ej2-inputs';

2. Configure the floating label by passing the HTML input element and floatLabelType property set to Auto (or another value) to the createInput method.

3. Set the placeholder for the input element either via the placeholder attribute or as a parameter to createInput. The placeholder text serves as the floating label content.

4. Optional: Add icons to enhance the input by passing the buttons property with the e-input-group-icon class to the createInput method.
