-| `debounce` | `string` | Debounce timeout between keypresses. Defaults to 200.
-| `add?` | `function` | Method to be executed when a chip is added. Sends chip value as event.
-| `remove?` | `function` | Method to be executed when a chip is removed. Sends chip value as event.
-| `chipBlur?` | `function` | Method to be executed when a chip is blurred. Sends chip value as event.
-| `chipFocus?` | `function` | Method to be executed when a chip is focused. Sends chip value as event.
