Properties

accessibleDescriptionRef

Type: string | null | undefined

Sets the aria-describedby attribute of the dialog.

By default, the text contents of all elements inside the message area are combined into the aria-description attribute. However, there are cases where this can confuse screen reader users (e.g. the dialog may present a password confirmation form). For these cases, it's better to associate only the elements that will help describe the confirmation dialog through this API.
