Custom Components

Customize calendar day cells and month navigation buttons with renderer callbacks.

Pass an Arc renderer to appearance.day on DateCalendar or popover DatePicker surfaces. Start from default_calendar_day and default_calendar_month_button to preserve keyboard behavior and selection styling, then wrap or extend the default output.

• Highlighting weekends, holidays, or blackout dates in the grid
• Compact month/year pickers with abbreviated labels
• Product-specific day badges (dots, counts) on calendar cells

• Define a function matching CalendarDayRenderer (or month button equivalent).
• Delegate to the default renderer for baseline interaction, then wrap with extra markup or classes.
• Assign Some(Arc::new(your_renderer)) to appearance.day on the calendar or date picker.
