WAI-ARIA
This section lists the selectors, attributes, and behavior patterns supported by the component and its composite elements, if any.
MultiViewCalendar Grid
The element wrapping the tables in the component should follow the requirements for the grid role (https://www.w3.org/TR/wai-aria-1.2/#grid).
| Selector | Attribute | Usage |
|---|---|---|
.k-calendar-view |
role=grid |
Specifies the role of the Calendar dates table. |
aria-labelledby |

|
aria-activedescendant=.k-calendar-td.k-focus id |
Pointing to the currently active (focused) date/month/year/decade cell in the table. | |
tabindex=0 |
Makes the grid focusable. | |
.k-calendar-table |
role=none |
All k-calendar-table elements must have their role set to none. That is because their content must be made belonging to a single grid component. |
.k-content:first-of-type>.k-calendar-head |
role=rowgroup |
The first k-calendar-thead must explicitly have its role set to rowgroup as its semantics has been removed while setting its <table> role to none. |
.k-calendar-tbody |
role=rowgroup |
The k-calendar-tbody elements must explicitly have their roles set to rowgroup as their semantics have been removed while setting their <table> elements role to none. |
.k-content:first-of-type>.k-calendar-head>.k-calendar-tr,.k-calendar-head>.k-calendar-tr |
role=row |
The k-calendar-tr elements must explicitly have their roles set to row as their semantics have been removed while setting their <table> elements role to none. Does not apply for fully empty rows, header rows after the first month, and initial data rows in Month views after the first month that have at least one cell missing |
.k-content:first-of-type>.k-calendar-head>.k-calendar-tr>.k-calendar-th |
role=columnheader |
The k-calendar-th elements must explicitly have their roles set to columnheader as their semantics have been removed while setting their <table> elements role to none. |
scope=col |
Specifies that the header is applied to a column. | |
aria-label |
Specifies the full name of the day of the week (the column header). | |
.k-calendar-td:not(.k-out-of-range) |
role=gridcell |
The cells must explicitly have their roles set to gridcell as their semantics have been removed while setting their <table> elements role to none. |
aria-label or title
|
Applicable in year view - for better context contains the full name of the month. May also be applied in month view to specify the full text for a date. | |
.k-calendar-td.k-selected |
aria-selected |
Specifies whether the date is selected or not. |
.k-calendar-td.k-disabled |
aria-disabled |
When a date is not available for selection, its gridcell element must have the attribute set to true. |
.k-content:first-of-type>.k-calendar-tbody>.k-calendar-tr:first-of-type>.k-out-of-range |
role=gridcell |
The cells must explicitly have their roles set to gridcell as their semantics have been removed while setting their <table> elements role to none. |
