Test

11.8.2

Description

Dans chaque balise <select>, chaque balise <optgroup> possède-t-elle un attribut label ?

Technical notes (criterion 11.8)

Il est possible d’utiliser une balise ayant un attribut WAI-ARIA role="listbox" en remplacement d’une balise <select>. En revanche, il est impossible de créer des groupes d’options via l’utilisation de WAI-ARIA. De ce fait, une liste nécessitant un regroupement d’options structurée à l’aide d’une balise ayant un attribut WAI-ARIA role="listbox" sera considérée comme non conforme au critère 11.8.
