If the form design contains lists created by nesting subforms in a form design, you can use the Accessibility palette to set the appropriate subform role for each subform that makes up the list so that the screen reader can announce the list, the number of list items, the nesting level, and the list end.For example, assign the role of List to the top-level subform and assign the role of List Item to the nested subforms that make up the list items.
