Vue Calendar Props

Default Value: undefined

The value of this property will be passed to the accesskey attribute of the HTML element that underlies the UI component.

activeStateEnabled

Specifies whether the UI component changes its state as a result of user interaction.

Selector: active-state-enabled

Type:

Default Value: true

The UI component switches to the active state when users press down the primary mouse button. When this property is set to true, the CSS rules for the active state apply. You can change these rules to customize the component.

Use this property when you display the component on a platform whose guidelines include the active state change for UI components.

cellTemplate

Specifies a custom template for calendar cells.

Selector: cell-template

Type:

template

Template Data:

Name	Type	Description
date	Date	A Date object associated with the cell.

Default Name: 'cell'

dateSerializationFormat

Specifies the date-time value serialization format. Use it only if you do not specify the value at design time.
