The header of the agenda is a canvas and an opportunity for customization. You can add custom components and enable new interaction in context. Such an example would be a custom filter block created with the help of a segmented control and placed between the standard UI components, which are: - **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`. ### 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.: ```css .mbsc-material .mds-header-filter-prev { order: 1; } .mbsc-material .mds-header-filter-next { order: 2; } .mbsc-material .mds-header-filter { order: 3; } .mbsc-material .mds-header-filter-today { order: 4; } ``` **Want to style and reorder the header?** [Take a look at the previous example →](https://demo.mobiscroll.com/angular/agenda/customizing-calendar-header) ## What this demo shows - Shows a monthly agenda view with events listed and grouped by date. - **Header navigation** The month and year label in the top left opens date navigation. A segmented resource filter is centered in the header. The previous and next arrows and the Today button on the right move between months and jump back to the current date. - **Resource filter** The segmented control contains three selectable options: `Barry`, `Hortense`, and `Carl`, each with an avatar shown before the name. - **Resource filtering** Selecting a resource from the segmented control, updates the month view to show that person's events, making it possible to show or hide events by resource from the header. - **Color coding** `Barry`'s option and events use green, `Hortense` uses blue, and `Carl` uses pink, so the active filter and the visible events stay visually aligned. - **Agenda list** The area below the header lists events for the selected month. Events in the agenda are grouped by date. - **Sticky day headers** As the agenda scrolls vertically, each day stays visible with a sticky date header while its events appear underneath. - **Events** Events appear as agenda cards with a colored strip on the left and the event title next to it. Start and end times are stacked on the right side of timed events. All-day events show the all-day label on the right. - **Event interaction** Hovering an event highlights it. - **Event selection** Clicking an event selects and highlights it. ## Best for - **Resource-specific month planning** Viewing one person's month schedule at a time without leaving the agenda view. - **Team agendas with simple filtering** Switching between a small set of people or resources from a compact header control. - **Color-coded resource views** Making it easy to distinguish which events belong to which resource. - **Operational dashboards** Internal scheduling tools where users need quick filtering and fast month-to-month navigation. - **Custom agenda toolbars** Cases where the standard header needs extra controls without moving filtering outside the agenda. ## API used in this demo - [`theme`](https://mobiscroll.com/docs/angular/eventcalendar/api#opt-theme) - option - [`themeVariant`](https://mobiscroll.com/docs/angular/eventcalendar/api#opt-themeVariant) - option - [`data`](https://mobiscroll.com/docs/angular/eventcalendar/api#opt-data) - option - [`headerTemplate`](https://mobiscroll.com/docs/angular/eventcalendar/api#template-headerTemplate) - template - [`resources`](https://mobiscroll.com/docs/angular/eventcalendar/api#opt-resources) - option - [`view`](https://mobiscroll.com/docs/angular/eventcalendar/api#opt-view) - option ## Code ### Component ```ts import { CommonModule } from '@angular/common'; import { HttpClient } from '@angular/common/http'; import { Component, OnInit } from '@angular/core'; import { FormsModule } from '@angular/forms'; import { MbscCalendarEvent, MbscEventcalendarView, MbscModule, MbscResource, Notifications, setOptions, } from '@mobiscroll/angular'; setOptions({ theme: 'ios', themeVariant: 'light' }); @Component({ selector: 'app-root', templateUrl: './app.component.html', providers: [Notifications], standalone: true, imports: [CommonModule, FormsModule, MbscModule], }) export class AppComponent implements OnInit { constructor( private http: HttpClient, private notify: Notifications, ) {} myEvents: MbscCalendarEvent[] = []; myResources: MbscResource[] = [ { id: 1, name: 'Barry', color: '#328e39', img: 'https://img.mobiscroll.com/demos/m1.png', }, { id: 2, name: 'Hortense', color: '#00aabb', img: 'https://img.mobiscroll.com/demos/f1.png', }, { id: 3, name: 'Carl', color: '#ea72c0', img: 'https://img.mobiscroll.com/demos/m2.png', }, ]; myView: MbscEventcalendarView = { agenda: { type: 'month' } }; filteredEvents: MbscCalendarEvent[] = []; selectedResources = [1]; onChange(ev: Event): void { const target = ev.target as HTMLInputElement; const resource = this.myResources.find((r) => r.id === +target.value); this.filteredEvents = this.myEvents.filter((e) => this.selectedResources.indexOf(e.resource as number) !== -1); this.notify.toast({ message: (target.checked ?

Define a `resources` array with 3 entries - each has `id`, `name`, `color`, and `img` (avatar URL). Pass it to the `resources` option. Load events from `https://trial.mobiscroll.com/filter-resource-events/` via JSONP using `getJson(url, callback, 'jsonp')`. Angular: use `HttpClient.jsonp()`. Each event has a `resource` field (integer ID) that links it to a resource. - Implement client-side filtering: maintain a `selectedResources` set (initially resource 1 only). After loading, compute `filteredEvents = myEvents.filter(e => selectedResources[e.resource])` and pass `filteredEvents` to the Eventcalendar's `data` option. Recompute and update `filteredEvents` whenever the selection changes. - Build a custom header via `renderHeader` (Angular: `headerTemplate`, Vue: `header` slot) containing: `CalendarNav` on the left, a `SegmentedGroup` with `select="multiple"` in the center (each `Segmented` shows the resource's avatar image + name), and `CalendarPrev`, `CalendarToday`, `CalendarNext` on the right. On segment change, update the `selectedResources` map and refresh `filteredEvents`. Show a Toast with "Showing/Hiding {name} events". ## Run it in your project 1.
