Scripting: List of ARIA Widget Relationships

Widget Relationships

  1. This list itemizes ARIA state attributes that links two ARIA widgets. To be listed, both elements in the relationship should be ARIA widgets, i.e. have defined role attribute, and one element should have one of the ARIA state attributes that define a relationship. See Relationship column description for the list of appropriate state attributes.
  2.     Selecting an item with colored background, by clicking on the item or by using the arrow keys, displays related accessibility statement in the Accessibility Information.
  3. Columns
    • From - The id attribute of the widget that has the relationship state attribute is displayed.
