There are 4 categories of ARIA states and properties:

1. Widget attributes

   • aria-checked
   • aria-disabled
   • aria-errormessage
   • aria-expanded
   • aria-haspopup
   • aria-hidden
   • aria-invalid
   • aria-label
   • aria-level
   • aria-modal
   • aria-multiline
   • aria-multiselectable
   • aria-orientation
   • aria-placeholder
   • aria-pressed
   • aria-readonly
   • aria-required
   • aria-selected

2. Live region attributes

   • aria-busy
   • aria-live
   • aria-relevant
   • aria-atomic

3. Drag-and-Drop attributes

   • aria-dropeffect
   • aria-grabbed

4. Relationship attributes

   • aria-activedescendant
   • aria-colcount
   • aria-colindex
   • aria-colspan
   • aria-controls
   • aria-describedby
   • aria-description
   • aria-details
   • aria-errormessage
   • aria-flowto
   • aria-labelledby
   • aria-owns
   • aria-posinset
   • aria-rowcount
   • aria-rowindex
   • aria-rowspan
   • aria-setsize

Some states and properties apply to all HTML elements regardless of whether an ARIA role is applied. These are defined as "Global" attributes. Global states and properties are supported by all roles and base markup elements.

Many of the above attributes are global, meaning they can be included on any element unless specifically disallowed:

• aria-atomic
• aria-busy
• aria-controls
• aria-current
• aria-describedby
• aria-description
• aria-details
• aria-disabled
• aria-dropeffect
• aria-errormessage
• aria-flowto
• aria-grabbed
• aria-haspopup
• aria-hidden
• aria-invalid
• aria-keyshortcuts
• aria-label
• aria-labelledby
• aria-live
• aria-owns
• aria-relevant
• aria-roledescription

By "specifically disallowed," all the above attributes are global except for the aria-label and aria-labelledby properties, which are not allowed on elements with role presentation nor its synonym none role.

The following are the reference pages covering the WAI-ARIA states and properties discussed on MDN.
