Target Resources Widgets with required owned elements
  • Required owned elements can be defined using the HTML DOM structure or the aria-owns attribute.
  • Use the DOM structure to add required owned elements by making them a descendant of the container element.
  • When the owned elements are not descendants of the container element, use the aria-owns attribute on the container element to reference the owned elements.
  • When aria-busy attribute is set to true on the container element, the container element does not need to own any required elements. aria-busy should be used when a container element is being dynamically populated.
  • NOTE: The DOM structure technique is preferred over the aria-owns technique, since it is less likely to result in authoring errors associated with creating and referencing elements with unique ids.
