Text, icon, buttons and other content can be grouped next to an input.
An InputGroup is created by wrapping the input and add-ons inside an element with a p-inputgroup class where add-ons also should be inside an element with .p-inputgroup-addon class.
Multiple add-ons can be placed inside the same group.
Buttons can be placed at either side of an input element.
Checkbox and RadioButton components can be combined with an input element under the same group.
