You can do it one of two ways; if you wanted a label of each calendar then you can just duplicate the module with the alternating title and calendar link.
EG:
module: "calendar",
header: "US Holidays",
position: "top_left",
config: {
calendars: [
{
symbol: "calendar-check",
url: "webcal://www.calendarlabs.com/templates/ical/US-Holidays.ics"
}
]
}
},
{
module: "calendar",
header: "Another Calendar",
position: "top_left",
config: {
calendars: [
{
symbol: "calendar-check",
url: "webcal://www.calendarlabs.com/templates/ical/Another-calendar-link.ics"
}
]
}
},
The other option is to place the links in the one calendar.
EG:
{
module: "calendar",
header: "US Holidays",
position: "top_left",
config: {
calendars: [
{
symbol: "calendar-check",
url: "webcal://www.calendarlabs.com/templates/ical/US-Holidays.ics"
},
{
symbol: "calendar-check",
url: "webcal://www.calendarlabs.com/templates/ical/AnotherCalendar.ics"
},
{
symbol: "calendar-check",
url: "webcal://www.calendarlabs.com/templates/ical/AndAThirdOneIfYouWant.ics"
}
]
}
}
