The following section explains you the steps required to create TextBox with icon and floating label.

TextBox:

Create a parent div element with the class e-input-group
Place input element with the class e-input inside the parent div element.

import * as React from "react";
import './App.css';
class App extends React.Component<{}, {}> {
    render() {
      return (
        // element which is going to render the TextBox
        <input className="e-input" type="text" placeholder="Enter Name" />
      );
    }
};

Floating label:

Add the e-float-input class to the parent div element.
Remove the e-input class and add required attribute to the input element.
Place the span element with class e-float-line after the input element.
Place the label element with class e-float-text after the above created span element. When you focus or filled with value in the TextBox, the label floats above the TextBox.

Creating the Floating label TextBox, you have to set the required attribute to the Input element to achieve the floating label functionality which is used for validating the value existence in TextBox. If you want to render the Floating label TextBox without required attribute then refer to the Floating Label without required attribute section.

import * as React from "react";
import './App.css';
class App extends React.Component<{}, {}> {
    render() {
      return (
        // element which is going to render the Floating TextBox
        <div className="e-float-input e-input-group">
            <input type="text" required/>
            <span className="e-float-line"></span>
            <label className="e-float-text">Enter Name </label>
        </div>
      );
    }
};

And refer to the following sections to add the icons to the TextBox.

With icon and floating label

Create an icon element as a span with the class e-input-group-icon, and the user can place the icon in either side of TextBox by adding the created icon element before/after the input.

For the floating label enabled TextBox add the icon element as first or last element inside the TextBox wrapper, and based on the element position it will act as prefix or suffix icon.

ReactDOM.render(<Default />, document.getElementById('input-container'));

To place the icon on left side of the TextBox, create a div element with the class e-input-in-wrap as wrapper to the input element and place the floating line, floating text, and right side icon element within it. Add the e-float-icon-left class to the TextBox container element.

With clear button and floating label

The clear button is added to the input for clearing the value given in the TextBox. It is shown only when the input field has a value, otherwise not shown.

You can add the clear button to the TextBox by using showClearButton API in textbox.

Floating Label without required attribute

You can render the Floating label TextBox without required attribute by manually float the label above of the TextBox using input events. You can manually float the label above of the TextBox by adding the below list of classes to the floating label element. The classes are:

Class Name	Description
e-label-top	Floats the label above of the TextBox.
e-label-bottom	Label to be placed as placeholder for the TextBox.

Multi-line input with floating label

Add the HTML textarea element with the e-input class to create default multi-line input.

Add the floating label support to the multi-line input by creating the floating label structure as defined in the initial section.
