## Description
You can customize how the header of the event calendar looks and how the components are arranged. Besides that you can also add custom functionality, like a segmented control that lets people switch between calendar and scheduler.
Use the [`headerTemplate`](https://mobiscroll.com/docs/angular/eventcalendar/api#template-headerTemplate) option for passing a custom template. There are predefined components - shorthands if you will - that can be used to assemble the header:
- **Navigation component** - ``. Use the `.md-header-filter-controls` CSS class for custom overrides.
- **Today button** - ``. Use the `.md-header-filter-today` CSS class for custom overrides.
- **Previous month button** - ``. Use the `.md-header-filter-prev` CSS class for custom overrides.
- **Next month button** - ``. Use the `.md-header-filter-next` CSS class for custom overrides.
For changing the order the controls are laid out, you only need to set up the `headerTemplate`. This example sets a consistent order and layout across all themes and shows a custom control at the far right end.
**Overriding the order for specific themes**
For a custom order on a theme to theme basis, you will need to use a little CSS. [Flex layout](https://css-tricks.com/snippets/css/a-guide-to-flexbox/) makes reordering easy. It's just a matter of setting the order in CSS. For material use the `.mbsc-material`, for windows the `.mbsc-windows` prefix and for iOS it is `.mbsc-ios` class. Eg.:
```
.mbsc-material .md-header-filter-prev { order: 1; }
.mbsc-material .md-header-filter-next { order: 2; }
.mbsc-material .md-header-filter-controls { order: 3; }
.mbsc-material .md-header-filter-today { order: 4; }
```

## What this demo shows
- A desktop month-view event calendar is shown with a custom header and a view switcher that toggles between calendar and scheduler-style layouts.
- **Header** The left side shows the currently displayed month and year. The center contains previous and next month navigation arrows with a blue `Today` button between them for jumping back to the current date. The right side contains a segmented control with a calendar icon selected by default and a list icon for switching views.
- **Event labels** Days with events display labels directly inside the month cells. Labels use different styles and colors to distinguish all-day events, multi-day, and timed events.
- **Overflow handling** The number of visible event labels depends on the available vertical space in the day cell. Additional events are moved into a popover and indicated by an `X more` label, where `X` represents the number of hidden events. Clicking it opens a popover that lists the remaining events for that day.
- **Label interaction** Hovering over or clicking an event label selects it and highlights the selected label. This is tru in both views, event calendar month view and the scheduler week view.
- **Day cell states** Hovering a day cell highlights the day number with a gray background, while clicking the empty part of the cell selects the day and highlights the day number with a blue background.
- **Month navigation** The month can be changed by clicking and dragging the calendar left or right.
- **Scheduler view** Selecting the list option from the segmented control switches the layout to a weekly scheduler view.
- **Scheduler view** The weekly scheduler shows the days of the week at the top, an all-day section for all-day events, and a 24-hour time grid for timed events.
- **Scheduler view** The current time is marked with a blue line in the time grid.
- **Scheduler view** The time grid can be scrolled vertically with the mouse wheel while the header stays sticky.
## Best for
- **Calendar and schedule switching** Interfaces where users need to move between a month overview and a more detailed weekly schedule from the same header control.
- **Desktop planning tools** Scheduling and planning screens designed for desktop use, where a full month grid and richer header controls fit naturally.
- **Operational scheduling** Team, resource, booking, or internal planning tools where users switch between high-level monthly planning and time-precise weekly scheduling.

## Implementation notes
- Define two view configs toggled by a state variable: calendar uses `{ calendar: { labels: true } }`; schedule uses `{ scheduler: { type: 'week' } }`.
- Use `renderHeader` (Angular: `headerTemplate`, Vue: `header` slot) to build a fully custom header with three zones:
- Left: `CalendarNav` for the month/year title
- Center: two flat icon `Button` components (`material-arrow-back` and `material-arrow-forward`) flanking `CalendarToday` - these replace the built-in `CalendarPrev`/`CalendarNext`
- Right: an icon-only `SegmentedGroup` with a `calendar` icon and a `material-list` icon for switching between views
- Track the currently displayed date in a `selectedDate` state variable, kept in sync via `onSelectedDateChange`. The custom prev/next buttons call a `navigatePage()` helper that computes the target date based on the active view: in calendar view, it adds or subtracts one month; in schedule view, it adds or subtracts one week. Update `selectedDate` with the result to drive navigation. JS/jQuery: call `inst.navigate(date)` instead of updating a bound prop.
- Load events from a remote endpoint using `getJson` and assign them to `data`; for the imperative API, call `inst.setEvents(events)` in the callback.
