Accessibility#

  • It is a real input, so Space toggles it, forms submit it and name, value and required work as usual.
  • The label is wired with aria-labelledby, so the description is announced as a description rather than as part of the name.
  • Indeterminate sets the native indeterminate property, which screen readers announce as mixed.
  • Without a label, pass an aria-label.
