jsx-a11y/aria-activedescendant-has-tabindex
💼 This rule is enabled in the following configs: ☑️ recommended, 🔒 strict.
aria-activedescendant is used to manage focus within a composite widget.
The element with the attribute aria-activedescendant retains the active document
focus; it indicates which of its child elements has secondary focus by assigning
the ID of that element to the value of aria-activedescendant. This pattern is
used to build a widget like a search typeahead select list. The search input box
retains document focus so that the user can type in the input. If the down arrow
key is pressed and a search suggestion is highlighted, the ID of the suggestion
element will be applied as the value of aria-activedescendant on the input
element.
Because an element with aria-activedescendant must be tabbable, it must either
have an inherent tabIndex of zero or declare a tabIndex attribute.
