Value to describe the component can either be provided with < i > aria - labelledby < / i > or < i > aria - label < / i > props . The multiselect component has a < i > combobox < / i > role in addition to < i > aria - haspopup < / i > and < i > aria - expanded < / i > attributes .
The relation between the combobox and the popup is created with < i > aria - controls < / i > attribute that refers to the id of the popup listbox .
< / p >
< p > The popup listbox uses < i > listbox < / i > as the role with < i > aria - multiselectable < / i > enabled . Each list item has an < i > option < / i > role along with < i > aria - label < / i > , < i > aria - selected < / i > and < i > aria - disabled < / i > attributes . < / p >
< p >
Checkbox component at the header uses a hidden native checkbox element internally that is only visible to screen readers . Value to read is defined with the < i > selectAll < / i > and < i > unselectAll < / i > keys of the < i > aria < / i > property from the
< router -link to = "/locale" > locale < / r o u t e r - l i n k > A P I .
< / p >
< p > If filtering is enabled , < i > filterInputProps < / i > can be defined to give < i > aria - * < / i > props to the input element . < / p >
< p > Close button uses < i > close < / i > key of the < i > aria < / i > property from the < router -link to = "/locale" > locale < /router-link> API as the <i>aria-label</i > by default , this can be overriden with the < i > closeButtonProps < / i > . < / p >
