Accessibility #

Screen Reader

SplitButton component renders two native button elements, main button uses the label property to define aria-label by default which can be customized with buttonProps. Dropdown button requires an explicit definition to describe it using menuButtonProps option and also includes aria-haspopup, aria-expanded for states along with aria-controls to define the relation between the popup and the button.

The popup overlay uses menu role on the list and each action item has a menuitem role with an aria-label as the menuitem label. The id of the menu refers to the aria-controls of the dropdown button.


<p-splitButton 
    [buttonProps]="{'aria-label': 'Default Action'}"
