SILK UI Framework



Calendar Pattern

The Calendar pattern provides you with a date and time picker with a flat UI to display inline on the screen. It can receive lists of dates with events and it allows selection within a range of days. The calendar was created using the Pikaday.js library.

You can use this pattern to display a list of elements side by side, with a different number of items per row on different devices.

How to Use the Calendar Pattern

Use static data or a List widget inside this block to display items in a gallery pattern.


1. Upon dragging the calendar to the page, you'll be prompted to create an event.

2. To have access to the picked date, you need to create an assign to the startDate (if SelectInterval is False).

3. Set the default value of the variable PickedDate as CurrDateTime().



Listing Events of a Selected Day

1. Set the area where you want to put the list of events.

2. Create an entity with a DateTime attribute.

3. Set the entity in your EventList parameter on eventList, using the right attribute to map.


4. Add the list to the page.


5. Create a Local Variable.


6. Get another Aggregate for the Events and set a filter on the aggregate:
DateTimeToDate(Events.DateTime) = Date
