                    style={{width: 170}}
                    date={this.state.date1}
                    mode="date"
                    placeholder="select date"
                    format="YYYY-MM-DD"
                    maxDate="2020-01-01"
                    minDate="2010-01-01"

                    confirmBtnText="Confirm"

                    customStyles={{
                    dateIcon: {
                        position: 'absolute',
                        left: 0,
                        top: 4,
                        marginLeft: 0
                    },
                    dateInput: {
                        marginLeft: 36
                    }
                    // ... You can check the source to find the other keys.
                    }}
                    onDateChange={(date) => {this.setState({date1: date})}}
