OverlayPanel component uses <i>dialog</i> role and since any attribute is passed to the root element you may define attributes like <i>aria-label</i> or <i>aria-labelledby</i> to describe the popup contents. In addition
|
||
|
|
<i>aria-modal</i> is added since focus is kept within the popup.
|
||
|
|
</p>
|
||
|
|
<p>OverlayPanel adds <i>aria-expanded</i> state attribute and <i>aria-controls</i> to the trigger so that the relation between the trigger and the popup is defined.</p>
