Max events per day

Use maxEventsPerDay prop to control how many events are visible per day before the "+more" indicator appears. The value is clamped between 1 and 10. Day cell height adjusts automatically.

}

Use onExternalEventDrop to allow dragging items from outside the component into the schedule. External items must set data in dataTransfer during their onDragStart. The callback receives the DataTransfer object and the drop target datetime.

}

Bidirectional drag and drop

Combine onExternalEventDrop with withEventsDragAndDrop to enable bidirectional drag and drop. Items dragged from the sidebar are removed from the list and added to the schedule. Events dragged from the schedule back to the sidebar are removed from the schedule. The schedule sets application/json with { eventId } in dataTransfer when an event is dragged, which the sidebar drop zone reads to identify the event.

Full event customization

Use renderEvent prop to fully customize event rendering. This function receives the event data as the first argument and all props that would be passed to the event root element (including children) as the second argument, allowing you to wrap events in custom components like HoverCard, Tooltip, or custom wrappers.

Background events

Set display="background" on an event to render it as a full-width, semi-transparent, non-interactive block behind regular events. Background events span the full height of the day cell in the month view.

Localization

Use locale prop to set the dayjs locale for date formatting. Combine it with labels prop to translate all UI text.

        moreLabel: (hiddenEventsCount) => `+${hiddenEventsCount} más`,

Create and update events

Set withDragSlotSelect prop to allow users to drag across day cells to select a date range. When the drag ends, the onSlotDragEnd callback is called with the range start and end dates. Combined with onDayClick and onEventClick callbacks, this enables a complete event creation and editing experience.

Responsive styles

MonthView uses @container queries for responsive styles. The component automatically adjusts its layout based on the container width, hiding labels and reducing padding on smaller screens. Container queries are supported in all modern browsers.

Accessibility

Focus management

In the MonthView component, focus is managed to provide an efficient keyboard navigation experience:

Only the first day in the month view is included in the tab order (has tabIndex={0})
All other days have tabIndex={-1} and can only be reached via arrow key navigation
Outside days (days from adjacent months) are navigable using arrow keys when withOutsideDays is true
Disabled days are skipped during keyboard navigation

This approach reduces the number of tab stops when navigating through the calendar, making it faster for keyboard users to move through the view while still allowing full access to all days via arrow keys.

Keyboard interactions

Note that the following events will only trigger if focus is on a day control.

Key	Description
`ArrowRight`	Focuses next non-disabled day
`ArrowLeft`	Focuses previous non-disabled day
`ArrowDown`	Focuses same day in the next week
`ArrowUp`	Focuses same day in the previous week

Day labels

Each day button has an aria-label attribute with the full date in the format "Month Day, Year" (e.g., "November 15, 2025"). This provides screen reader users with complete date information.
