- Resource support
- Templating
- Customizable day, week, month views
- Built in resources
- Event D&D with CRUD operations
- Daily, monthly, yearly event list
- Combine with week calendar
- Templating
The calendar view supports everything from single to multiple week views all the way to month grids with various ways to render events.
The four views - scheduler, calendar, timeline, agenda - can be combined to create the perfect user experience on mobile, desktop and on everything in-between.
The capabilities like recurring events, all-day, multi-day events, responsiveness are supported by all views.
As part of Event calendar and scheduler it can be picked up with the Scheduling & calendaring and Complete licenses.
Calendar - Mobile month view
Use the event calendar for mobile, desktop and everything in-between. The content perfectly fills the parent container or the mobile screen in full width.
You can chooose to render an agenda below the calendar broken up into days ordered chronologically. All of this is configured in the view option.
You can use the calendar and agenda together or separately. For more ways to use the agenda learn about how to configure it.
Calendar - Desktop month view
Desktops or larger screens provide more space, which means you can use not just the horizontal but vertical space as well. Horrizontally the calendar grows to fill the full width of the parent container while the height can be adjusted through the height option.
The number of visible labels are determined by the available space and the ones that don't fit will be shown in a popover. To save vertical space you can show all events in a popover.
Calendar - Responsive
The event calendar is fully responsive. It adapts to the available space and fills the screen to look good everywhere. While the you don't have to worry about the width the height can be manually adjusted with the height option.
Use the responsive option to configure how the calendar behaves on different sized screens.
The responsive option is equipped with five breakpoints -
xsmall (up to 575px),
small (up to 767px),
medium (up to 991px),
large (up to 1199px),
xlarge (from 1200px).
Custom breakpoints can be added if necessary: my-custom-breakpoint: { breakpoint: 600 } (from 600px up to the next breakpoint).
Calendar - Print mode
The event calendar includes print optimized styling through the print add-on. This needs to be added to the download package or installed separately from a dedicated NPM package.
Print styling is applied when someone prints the page that contains the calendar. In addition to that, you can call the print method on the instance which grabs only the markup of the calendar, places it onto a temporary page and calls the browsers printing function. This is especially useful when you want to add a button to only print the calendar rather than the whole page.
Besides printing, PDF export is possible though the print dialog of the browser.
Calendar - Events as labels
Events can be displayed in a couple of different ways. Most of the time showing the event data inside and across the calendar cells is the way to go. When configuring the calendar object, you can set labels: true. All of this happens under the view option.
The number of visible labels are determined by the available space and the ones that don't fit will be shown in a popover. To save vertical space you can show all events in a popover.
Calendar - Events in popover
Besides displaying events as labels, you can have them show up in a pop-over. Set it up though the calendar: {popover: true} object inside the view option.
Using the popover setting saves vertical space and provides a subtle cue to the user that there are events. A small dot will apear in day cells with events or if calendar: {count: true} is set, an event count is displayed.
The same popover is rendered when events are displayed as labels and not all fit vertically in the calendar day cells.
Calendar - Custom event order
When rendering events, they follow the same order: all-day events at the top followed by everything else sorted by the event start time. Events with the same start are ordered alphabetically by title.
The default logic can be overriden using the eventOrder option which expects a function that compares two events and returns an order (-1 or 1). This can be useful in scenario where rendering PROPOSED vacation at the top followed by APPROVED time off is more useful.
Calendar - Timezones
The event calendar works with local times by default, but ships with support for changing the timezone. The conversions and correct output relies on either of the two external libraries: luxon or moment-timezone. For installing and using these libraries check out this guide.
There are two angles regarding timezones:
dataTimezone- the calendar expects this format and returns this format. It is'local'by default if the date-times don't contain any timezone informationdisplayTimezone- the calendar displays the events in this timezone. The date-times will be converted from thedataTimezoneand displayed accordingly. It is'local'by default
Calendar - Switching timezones
If the context requires users being able to change the timezone on the fly, you can add a custom dropdown with the desired timezones to the event calendar header. This can be of course placed externally to the calendar as well, eg. setting page.
Set the timezone of the incoming data through the dataTimezone - eg. 'utc', and set the display timezone thorugh the displayTimezone - eg. 'America/Los_Angeles'
Calendar - Month or week view
The calendar view supports variable weeks. Save space by only displaying one or two weeks or go for a full month where it makes sense.
Use the type and size properties of the view
option to set the size of the month or week view.
Calendar - Multi-month or year view
Besides the single month view, the calendar can be configured to render multiple months or a year. Controlled thorugh the calendar.type and calendar.size properties of the view option.
Depending on the height of the parent container the calendar is rendered in, the header that can be used for navigation is sticky at the top while the months are vertically scrollable.
Calendar - Colored backgrounds
Color the background of the days with the colors option.
You can specify backgrounds as exact dates, ranges or set up recurring rules. The recurring object works the same way as for the events.
Use the onPageLoading lifecycle event to color backgrounds runtime. You can learn about lifecycle events and places where to drop logic to customize the experience.
Calendar - Switching views
Dynamically switch views within one calendar instance. Use a UI control to let users do the switching or do it programatically. This example features a segmented component inside the header, but the live option changes can be invoked from anywhere.
Switch between a month view with a monthly agenda, a week view with a weekly agenda and daily event list.
Use the setOptions method to dynamically update any option.
Calendar - Custom event labels
You can customize the look of the labels and show addtional content besides the event.title. There are two approached you can take:
- Only customize the content of the labels - For this you will want to use the
renderLabelContentoption. Thecolorand positioning of the label will be handled by the calendar. Thetitleand any other custom fields you want to show inside the label is your responsability. - Fully customize how the labels look (like in this example) - Use the
renderLabeloption. All original event fields along with computed fields likeisMultiDay,lastDaycan be leveraged for constructing the render function. With therenderLabelyou will have full control over how the labels are styled including things likecolor,titleand any custom fields.
Calendar - Custom events in popover
The events listed in the popover can be customized in two ways:
- Full event customization (like in this example) - The calendar handles the rendering of events in the correct order. Styling the content, colors and everything else is your responsability.
- Content customization - The calendar prints the
startandendtimes,allDayand sets the appropriatecolor. Content like title and other fields can be shown.
You can provide styling to the title field and any other custom fields like description, location, participants ...
Pass a rendering function to the renderEventContent option. All original event fields along with computed fields like isMultiDay, lastDay are passed to the function. For a fully custom event rendering use the renderEvent option.
If you add custom markup you will want to add styling too. Use the popoverClass under the view option to tell the calendar what CSS class it should append to the popover container so that you can write specific CSS rules.
Calendar - Customizing the header
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 renderHeader option for passing a custom header layout. There are predefined components - shorthands if you will - that can be used to assemble the header:
-
Navigation component -
<div mbsc-calendar-nav></div>. Use the.md-header-filter-controlsCSS class for custom overrides. -
Today button -
<button mbsc-calendar-today></button>. Use the.md-header-filter-todayCSS class for custom overrides. -
Previous month button -
<button mbsc-calendar-prev></button>. Use the.md-header-filter-prevCSS class for custom overrides. -
Next month button -
<button mbsc-calendar-next></button>. Use the.md-header-filter-nextCSS class for custom overrides.
For changing the order the controls are laid out, you only need to set up the
renderHeader.
This example sets a consistent order and layout across all themes and shows a custom control at the far right end.
For a custom order on a theme to theme basis, you will need to use a little CSS. Flex layout 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; }Calendar - Custom event tooltip
There are several approaches to showing a tooltip when hovering events.
The native tooltip
By default, the calendar shows the browser native tooltip when hovering the event. This includes the times and title of the event, which does the job most of the times.
For showing a custom text use the tooltip property of the data object. This tooltip is specific to every event.
If you want to hide the native tooltip, you can set the showEventTooltip to false.
Setting the showEventTooltip to false gives room for a fully custom tooltip that can be implemented by using the
onEventHoverIn and onEventHoverOut
lifecycle events. With the help of the Mobiscroll popup you can show a custom tooltip that holds details, actions applicable to the event it is anchored to.
Calendar - Move, resize & create
Drag & drop is a core feature of the event calendar and it is composed of four sub-features:
- Click to create events - double click to create events. This can be turned off or set to single click
- Drag to create events - tap/click to start creating an event and drag to the desired length
- Move events - grab an event and move it wherever needed
- Resize events - change the length of en event, grab it from either end and resize it
You have granular control over features through the
clickToCreate,
dragToCreate,
dragToMove and
dragToResize options, which are false by default.
Events can be marked as fixed by setting their editable property to false. This turns delete, drag & drop move and resize off for the event.
Calendar - Manage blocked out dates
Entire days and ranges can blocked out to manage event creation and editing more efficiently.
To disable specific or recurring days you can pass an array to the invalid option. A couple of examples:
- To disable weekends, use the recurring object -
recurring: { repeat: 'weekly', weekDays: 'SA,SU' } - Disable a specific range -
{ start: new Date(2020, 11, 19), end: new Date(2020, 11, 20) }
When dragging events onto disabled days, they will automatically be denied and
onEventCreateFailed/
onEventUpdateFailed
events will be triggered, from which custom logic can be executed to show a toast or maybe a modal for data correction. The built-in logic of how the calendar handles validation on user interaction can be controlled through the invalidateEvent option:
'strict'- Strict being the default, no event overlap is allowed with invalid ranges.'start-end'- With start-end validation the calendar checks if the start or end of the event coincides with any invalid range. Other overlaps are allowed.
If you're interested in invalids for a given range (including recurring occurrences), you can use the getInvalids function.
Calendar - External drag and drop
Events can be created and scheduled by dragging and dropping an external resource onto the calendar. In order for that to work you will need to have two things set up:
- Enable the calendar to receive external events by setting
externalDroptotrue. - Initialize the external events (containers) as
draggablecomponents.
Set up a container as draggable with the mbsc-draggable attribute. Pass a skeleton event definition through the data-drag-data attribute as a stingified json object. This will be added to the event calendar on drop. If omitted, a default event will be created. For a more programmatic approach you might want to use the component initialization where the draggable is initialized in js code and the dragData can be passed as an object.
Learn more from the external drag & drop documentation.
Use the onEventCreate and onEventCreateFailed for triggering a custom logic on drop like showing a toast. The appropriate lifecycle event will be triggered if the drop is successful or fails.
Calendar - External d&d presets
Use external draggable events to create preset tasks that people can quickly copy and spawn events from. A great example is a car wrapping shop where different jobs need to be set up depending on the type of vehicle.
Print a list of predefined tasks and initialize them as draggable elements.
Enable externalDrop for the calendar and set up the predefined event skeletons for the
draggable component.
Whenever there is more information to be captured, like a detailed task notes, customer information, the name of the technician... you can trigger a popup with the task form in the onEventCreate lifecycle event. For failed drops (trying to schedule a task during lunch breaks or weekends) the onEventCreateFailed event will be triggered.
Calendar - Event properties
The event data structure for the calendar is straightforward with a couple of base properties that the component understands and uses to render the UI. Besides the base properties you can add any custom property, like location, description ...
id- A unique ID for the event. If not specified a unique id will be generatedtitle- Defines the event text. This can be plaintext or HTMLtooltip- Defines the text for the tooltip which appears on mouse hover. If not specified, it will show the title and the start/end times of the event.color- Defines the event colorstart- Sets the start date and time for the event. It can be a js date object, ISO date string or moment.js object. Learn about date formatsend- Sets the end date and time for the event. The same formats are supported as forstartallDay- Configures the event as a full-day eventrecurring- Configures the recurring rules for the event. Learn about recurring eventsresource- Links the event to one or more resources. Expects a list of IDs part of theresourcesarray.editable- Denotes if the event is editable. If settrue, the event cannot be dragged, resized or deleted even if globally enabled
Calendar - Supported date formats
Understanding how to work with dates inside the event calendar is essential.
You can pass to the data, marked, colors and labels in four different formats.
The event calendar can work with Javascript date objects, ISO strings and Moment.js objects.
Calendar - Recurrence rules
Configure daily, weekly,monthly and yearly recurring events. On top of setting up recurrence, you can exclude specific and recurring days. This is especially useful in cases when a single occurence of an event is deleted or is moved to a different time.
You can pass the recurrence rule in the recurring property of the event as an object or a string in RRULE format. Learn about the event data structure and where to place the recurring rules.
Use the configurator to experiment, build strings and objects that you can grab and use.
Calendar - Loading inline data
What is an event calendar without any events in it? To populate it with events all you have to do is pass the event array to the data option.
In a real-world scenario you would probabaly load the events from a remote resource or event better, load them on demand. However the point of this example is to understand how easy it is to add events to the event calendar.
Calendar - Events from remote API
The calendar can be populated by passing an array to the data option, that you can construct either inline or by getting it from a remote API. The important thing to remember is that events need to be in a format that the calendar understands.
Calendar - Loading events on demand
The event calendar supports remote and local data sources. Besides that, events can be populated on initialization or loaded on demand.
Getting the events in real time as the user navigates improves load performance and always serves the most recent data.
Use the onPageLoading lifecycle event to load the data runtime. You can learn about lifecycle events and places where to drop logic to customize the experience.
Calendar - Events from Google calendar
Event data can be loaded from remote sources. Even if initially you don't get it in the same format the calendar understands, you can easily convert it. Set the base properties and custom fields and let the calendar render the events or create custom event templates.
In this example you'll see how you can load events from a public calendar using the googleSDK. Make sure to set your API key and Client ID, that you can get from here.
Calendar - Add/edit/delete events
After looking at the different operations of event creation, edit/update and delete it all can be all put together in a choesive example.
Drag to create and click to create is enabled. Events can be created by dragging or with double click. As soon as the initial posion is confirmed, a temporary event is created and a custom edit dialog is shown for refinement. On cancel the temporary event will be removed and on confirmation the event will stay in the calendar.
Drag to resize and drag to move is enabled. Events can be reordered and resized. In addtion to that, clicking on the event will open a custom dialog that enables editing the various properties.
Delete can be implmented inside the edit dialog with a button. It's just a matter of removing it from the data object. If a dialog is not shown on click, focused events can be deleted with the backspace and delete keys.
Calendar - Recurring event editor
As seen in the previous example, an add/edit from can be created with custom and base event fields. While the CRUD example features delete with undo, this example shows off how to build a fully customizable recurrence editor right in the add/edit screen.
Above some common presets, like Daily, Weekly on X day, Monthly on Xth, Annually on the same day, Every Weekday a fully custom recurrence editor is implemented.
Copy & paste or delve into the code and understand how to generate recurrence objects or RRULES as seen in this live rule builder.
Calendar - In-header filtering
The header of the event calendar 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 -
<div mbsc-calendar-nav></div>. Use the.md-header-filter-controlsCSS class for custom overrides. -
Today button -
<button mbsc-calendar-today></button>. Use the.md-header-filter-todayCSS class for custom overrides. -
Previous month button -
<button mbsc-calendar-prev></button>. Use the.md-header-filter-prevCSS class for custom overrides. -
Next month button -
<button mbsc-calendar-next></button>. Use the.md-header-filter-nextCSS class for custom overrides.
For changing the order the controls are laid out, you only need to set up the
renderHeader.
For a custom order on a theme to theme basis, you will need to use a little CSS. Flex layout 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; }Calendar - Theming capabilities
The look and feel of the event calendar can be deeply customized. There are four levels of customization:
- Base themes: Choose between iOS, Material and Windows.
- Light or dark: Every theme has a
lightanddarkvariant. Setting thethemeVariantto'auto'will switch based on system settings. - Custom themes: Use the theme builder to customize the colors and make it match your brand.
- Custom CSS: If you need further customization, the sky is the limit with CSS overrides.
You can also see how every example looks by changing the theme from the header.
Calendar - Localization
The components are fully localized. In case of the event calendar this covers date and time format, button copy, rtl and more. You can see how each example shows up by clicking on the small flag icon or checking the examples below.
Calendar - Calendar systems
The event calendar supports multiple calendar systems. You can control it with the calendarSystem setting, and it supports the following options:
- Gregorian - it is included by default
- Jalali - it is the default system of the Persian calendar and is inlcuded within the Farsi language pack
- Hijri - it is included in the Arabic language pack
Calendar - Lifecycle events
The event calendar ships with different hooks for deep customization. Events are triggered through the lifecycle of the component where you can tie in custom functionality and code.
While users interact with the UI events like onEventClick, onInit, onSelectedDateChange ... will be triggered.
