aria-disabled
Indicates that the element is perceivable but disabled, so it is not editable or otherwise operable.
Widget attributes are specific to common user interface elements found on GUI systems or in rich internet applications which receive user input and process user actions. These attributes are used to support the widget roles.
Widget attributes might be mapped by a user agent to platform accessibility API state, for access by assistive technologies, or they might be accessed directly from the DOM. User agents MUST provide a way for assistive technologies to be notified when states change, either through DOM attribute change events or platform accessibility API events.

Global states and properties are supported by all roles and by all base markup elements.
Description
Indicates that the element is perceivable but disabled, so it is not editable or otherwise operable. See related aria-hidden and aria-readonly.
For example, irrelevant options in a radio group may be disabled. Disabled elements might not receive focus from the tab order. For some disabled elements, applications might choose not to support navigation to descendants. In addition to setting the aria-disabled attribute, authors SHOULD change the appearance (grayed out, etc.) to indicate that the item has been disabled.
The state of being disabled applies to the current element and all focusable descendant elements of the element on which the aria-disabled attribute is applied.
