For example you can set a input date with today: <TextfieldWithFloatingLabel onFocus={this.dataRegistrazioneOnFocus} value={this.state.dataRegistrazione} placeholder="Data registrazione (aaaa-mm-gg)" />

Initialize date using state in constructor with a function getToday() constructor(props) { super(props); this.state = { dataRegistrazione: getToday(), } }
