ARIA roles used must conform to valid values
How to Fix the Problem
Ensure all values assigned to role=""
correspond to valid ARIA roles.
Available roles by type are:
- Landmark: article, banner, complementary, main, navigation, region, search, contentinfo
- Widget: alert, alertdialog, application, dialog, group, log, marquee, menu, menubar, menuitem, menuitemcheckbox, menuitemradio, progressbar, separator, slider, spinbutton, status, tab, tablist, tabpanel, timer, toolbar, tooltip, tree, treegrid, treeitem
- Pseudo HTML: button, button, checkbox, columnheader, combobox, contentinfo, form, grid, gridcell, heading, img, link, listbox, listitem, option, radio, radiogroup, row, rowgroup, rowheader, scrollbar, textbox
- Document: document (when creating a document region inside an other type of region)
- Application: application (only around a widget to enable normal keyboard shortcuts for page content)
- Presentation: presentation (to cancel the native role of the element)
- Other Semantic: math, definition, note, directory
- Abstract: command, composite, input, landmark, range, section, sectionhead, select, structure, widget
Why this is Important
Rule Description
Values assigned to ARIA role values must be valid. Role values must be spelled correctly, correspond to existing ARIA role
values, and must not be abstract roles to correctly expose the purpose of the element.
The Algorithm (in simple terms)
Checks all elements that contain the WAI-ARIA role attribute to ensure that the role value is valid
