headerToolbar
Defines the buttons and title at the top of the calendar.
Object/false, default:
{
start: 'title', // will normally be on the left. if RTL, will be on the right
center: '',
end: 'today prev,next' // will normally be on the right. if RTL, will be on the left
}Setting the headerToolbar options to false will display no header toolbar. An object can be supplied with properties start/center/end or left/center/right. These properties contain strings with comma/space separated values. Values separated by a comma will be displayed adjacently. Values separated by a space will be displayed with a small gap in between. Strings can contain any of the following values:
title : text containing the current month/week/day
prev : button for moving the calendar back one month/week/day
next : button for moving the calendar forward one month/week/day
prevYear : button for moving the calendar back on year
nextYear : button for moving the calendar forward one year
today : button for moving the calendar to the current month/week/day
a view name, like dayGridMonth : button that will switch the calendar to any of the available views
Specifying an empty string for a property will cause it display no text/buttons.
