RangeCalendar, How can i set initial panels without initial values

[walker27]

Here is a scence: when we use dateRangePicker, we disabled furture date, and did not set initial values, but the panel show current month and next month. how can i change panel to prev month and current month

I'm now using an ugly workaround that sets a start date in the previous month when opening the calendar, and shortly after changes it back to the correct value. Relevant section:

onStartOpenChange(open) {
  if (open && this.state.start.format("MYYYY") === moment().format("MYYYY")) {
    const dummyStart = this.state.start.clone().startOf("month").subtract(1, "day"),
          startFixer = function() {
            const f = function() {
              this.setState({ dummyStart: null });
            };
            setTimeout(f.bind(this), 50);
          };

    this.setState({ open: true, dummyStart: dummyStart }, startFixer.bind(this));
  } else {
    this.setState({ open });
  }
}

render() {
  const calendar = (
    <RangeCalendar
      onSelect={this.dateSelected}
      showWeekNumber={false}
      defaultValue={[this.start, this.end]}
      locale={enUS}
      showOk={false}
      showDateInput={false}
      showToday={false}
      showClear={false}
      disabledDate={disabledAfterToday}
    />
  );

  return (
    <div className="picker-component">
      <Picker
        onOpenChange={this.onStartOpenChange.bind(this)}
        value={[this.state.dummyStart || this.state.start, this.state.end]}
        animation="slide-up"
        calendar={calendar}
        open={this.state.open}
      >
        {() => {
          return (<button className="button primary"></button>);
        }}
      </Picker>
    </div>
  );
}

It's for when the initial values are both in the current month, but I think that is the same case as with the default values (today).
