I tested my website with one of the accessibility tools. As the result it reported that my website menu is not compliant because:
Elements that behave as buttons but are built using other tags such as span, div, a or others, should include a "role" attribute that equals to "button".
In fact, this is a general <li> tag that has no click actions or whatever.
<div class="ch-wp-menu-item-dropdown-wrapper">
<ul class="ch-wp-menu-item-dropdown">
<li class="ch-wp-menu-item-dropdown-content">
{% for subItem in item.values %}
<div class="ch-wp-menu-item-subitem">
<ul>
<li class="ch-wp-menu-item-subitem-title" tabindex="0"> //the element that accessibility tool refers to
{{subItem.name}}
</li>
{% for value in subItem.values %}
<li>
<a href="{{value.value}}"
tabindex="0"
aria-label="{{value.name}}">
<div class="ch-wp-menu-item-subitem-record">{{value.name}}</div>
</a>
</li>
{% endfor %}
</ul>
</div>
{% endfor %}
</li>
<div class="ch-wp-menu-item-dropdown-backdrop"></div>
</ul>
</div>
Could you advise what might be the reason for this error?
