Kalendae：如何选择多个范围

Question

new Kalendae(document.getElementById("calendar"), {
    // new Kalendae(document.body, {
    months:4,
    mode:'range',
    direction:'today-future',
    selected:
    [
    //September-October
    Kalendae.moment(('2018-09-03')), Kalendae.moment(('2018-10-21')), Kalendae.moment(('2018-11-05')), Kalendae.moment(('2018-12-23')) ]
});

问题在于我尝试选择两个范围，但默认情况下只允许选择一个范围。提前谢谢！
